This really helped me because all my teacher does is put videos and doesnt even teach. Then she gets mad at us if we don't know the answer. I get some people learn better that way but I need someone to take it slow and explain just a bit. You really helped me and she has never showed us that method so im relived because we have a major test tomorrow. :)
LOL KILLED ME WHEN YOU PULLED OUT THE UMBRELLA. You are a real pal man, super appreciate this one, ax^2 factoring has always escaped me, and im in 4th quarter calculus!
Haha right
He gonna get bad luck for the rest of his life
I'm going back to college after a 10 year hiatus so I am faced with the COMPASS test. FOIL is easy enough but the drudgery of factoring was a dark cloud on the horizon. Thank you for keeping me dry on the rainy days ahead.
where did rainy days come from?
Genius... It seems like most professors just want to confuse the heck out of their students. I guess it makes them feel smarter.
You, my friend, are not like most professors.
he looks like john travolta
It is ver encouraging to hear how our videos have helped. We are in the process of making many many more. If there is something you would like to see please let us know.
I learned this method but in a less organized way, so I'm loving this.
Right on. I'm 47 and I remember this but my son is doing this and I swore there was an easier way. So I go to youtube and I find this guy. Umbrella. Loved it. I'm showing my son the same way. Great job buddy!
Opening an umbrella inside is bad luck. Im not gonna trust this
Evan P hey buddy...sameeeee
This is probably the easiest, yet simplest way to factor, EVER!! I wish more teachers taught this way!
Thank you. I'm 16 in AP algebra 2/trigonometry and I've understood more from you then my own teacher. You rock!!!!!!!!!!!!
It looks like its a rainy day so Its good thing that I brought my umbrella(whips out umbrella)
the umbrella scared the fuck out of me
the umbrella was honestly my favorite part lol
Wow, you really have a lot of things to say don't you.
Honestly since my comments were not directed towards you and merely just feedback for the producer of this video you should just refrain from touching the keyboard when pertaining the intention to digitally communicate to me because of the fact your responses simply mean absolutely nothing to me. (just some advice) if you continue I will not respond because obviously your not getting the point Smith.
im sorry if you got the impression i'm trying acting tough, I was actually just expressing my current state of emotion towards this poorly constructed example of how to use mathematical systems.
also so what if I made a once in a while grammatical error. Leave my comments alone there not directed or intended for you to respond to.
Because there is no way to find two numbers that add up to 12 and multiply to 105, simultaneously!
Or more generally:
To be factorizable the polynomial must have roots or become equal to zero at some point.
The Factor Theorem.
x − r is a factor of a polynomial P(x) if and only if r is a root of P(x).
Instead of the box method you could simply divide the two numbers you get when using the umbrella method by the coefficient. You then take the denominator of each and put it in front of the variable when you write the final answer. Example: if you have 3 and six, you divide by the coefficient 2. You get 3/2 and 3. So the final answer would be (2x +3)(x +3)
WTF!!!!! Now he is talking about an umbrella and his feelings. This guy must be the worst teacher EVER!!! He just doesn't stop getting off topic and starts talking about irrelevant topics like umbrellas, the sun, and his feelings.
This is the coolest way to factor ever. My teacher explained it to us in some super boring way, and then i was just like "BAM. check out this umbrella method i got off of youtube" and now half of the class uses it. Thanks for the help!
This is so much help to students who find it hard to understand factoring. But at 6:10, you should have said "6 divided by 3 equals 2 and -21 divided by 3 equals -7 and also the other column"... Anyway, I find your method useful. Great vid!
all these positive comments about online tutoring is obvious, there needs to be a new system of education, the one we are in right now sucks, because we cant learn from it, and i know the government knows this.
thankyou so much im in 8th grade and im struggling! we hav our finals this week too the only problem with this is that i dot hav enuff space and time becuz everyone always finishes before me and im always last
I just can't stop complementing, but I am not trying to flatter. I never got this is in school but I learned and understood by watching this video than learning at school. You're really good at teaching, SO......ROCK ON!
thank you sir my math teacher explain it way different and it was more simple according to her but this is better i believe i could succed in math im a freshman and im still stuck in algebra 1 thanks!!
Why cant every teacher be like you? You make so much sense man. Math is my worst subject and she's been teaching us this section about polynomials for a week and i barely understood it. Then i watched your videos and understood it in a few minutes! thanks again bro.
Thank you very much for doing this video! I have been using all your videos to help me through my homework. I never understood polynomials after last fall when a teacher explained it very badly! Now I understand I am very grateful!
You are amazing!!!! I am a visual learner and I have not been able to catch on to factoring, until now! I can see what I need to do! Thank you so much! I could just hug you!
So in the box, I have the same problem, but instead of 2x^2+9x+9, I have 2x^2+9x+10.
Instead of a 6 on the btoom left of the box, it's a 5. How does 2 go into 5?
But arent you still using guess and check when getting the -21 and -10 on the second problem? that s the part that im having trouble getting
I never realized mathematicians were so comical ...you have me rolling!....looks like a rainy day?...Good thing I brought my umbrella....Classic
i remember this but when you did the x and the numbers i remember i put variables inside the x to but forgot if this is the same i don't know
This was helpful. I forgot how to do it since I did this in 9th grade. I just wrote down the steps and put a number by the first example and then for the second one I looked at the notes and kept going from there!
I have been struggling in math for a month now because I didnt understand my teachers very stupid method. THis video is so helpful!
dude If you were my teacher I might actually be passing cause You Actually Teach!! Unlike My Teacher Who Doesn't clarify nothing!
dude,i wish i could hug you. Your vidz are so helpful!! And it is true im am learning more from this guy than my teacher. :)
i hope you realize the only reason you have so few views is because we only watch it once and get it, so thanks a bundle!
WAIT WAIT THANK YOU SO MUCH YOU'RE SO AWESOME YOU CAN STAND UNDER MY UMBUH-RELLA
Love ur positive behavior in teaching the umbrella method may help in some cases but its just a bit of a complex way of solving it but great strategy though
Let me first start by saying I'm a grown man who was driven to the point of violence because i've been struggling with this very topic since HS, this has attributed to me failing numerous math classes and being stuck in community college forever. SIR you are in every sense a true teacher , you took a subject i dreaded hated and made it so simple. This method is perfect for you if your learned how to foil with the box method like I did
Guess and check is sooo much more faster and efficient. I used to do the x^2 + mx + px + mp method (breaking up middle term and grouping) but guess and check is a LOT easier and much better when you get to trig.
It doesn't work with every polynomial. It's better to use quadratic formula.
factor 12xsquared+13x+3 because I don't know how . I get stuck on finding the greatest common factor part!
Thank you very much kind sir. Lol my math teacher showed our whole class this video, and we all loved it.
God Bless YOU. You total helped me, I didn't have to guess even though I missed my teacher teaching this.
Help! WHERE 9 COME FROM IN ORIGINAL PROBLEM? IF I CHECK ANSWER I GOT 2squared +3x+9
Thx so much at my school nobody in my class wanted to show me how to do this thx so much ur awesome
I dont understand what you are trying to say , you should reword this sentence/ unnecessary response.
(1x squared + bx + c) This was the first problem I tried on my homework and the foil did not check?
my class has tried learning this for weeks and i just learned it in less than 7 min....... omfg tysvm
i have a problem i tried it with this problem im still confused the problem was 4x^2+17x+4 plz help
This video deserves WAY more views. This is so much easier than the way my teacher teaches it. (:
Fantastic...I learned it another way but this is absolutely the better way (faster too). Thanks!
to many steps . I don't have time for that one problem . I need a faster way to do the problem .
THIS guy should be my IB math studies teacher! I learn so much better from him..plus he's funny.
That's it you are now my new math teacher! THANK YOU!!
so ggod teaching! i get it so fast unlike my teacher it takes me more than ! hour to learn it
So confusing!!! Just do the problem!
Other than the quadratic formula, there actually is another faster and easier way to factor.
I always forget factoring and ive actually never seen this umbrella method. Very cool stuff!
Can you ALWAYS use the umbrella method, even the greatest common factor could be taken out?
Now this is easy for me my teacher wouldn't really explain it he did one example and the he would give us a whole page to do which is not helpful but this is very helpful thank you
Looks like a rainy day huh? Well its a good thing....(swoosh) I brought my umbrella. xD
FFS! Why can't every teacher teach this method! My life has become easier! Thank u so much!
Thank you sooo much! I've understood more from you then from any of my math teachers! :D
Wow I have been to tutor zone for a long time I was in the commercial and I can't find it anyone have a link so I can cringe at my self?
Great info, i just hope you didn't get cursed with rainy days opening the umbrella inside. #BadLuck lol
This should be labeled trinomial since it's terms are limited to 3. Polynomial exceeds three typically
Im in intermediate Algebra 121 in College, and this is Brilliant. You are a life saver!
Omg. Youre so cool. Its alot easielike this. And you explain very well. :) likelikelike
This really helps me in my 8th grade Algebra 1 class. The method we were using was the guess and check and it is making me fail the class.
I"m here because i fell asleep in class and am now cramming for a test, brilliant.
Mrgodzilla it sounds like you are going to my school cuz thats how my teacher is XD
FUCK YES. im taking my accuplacer for college and you helped soo much. ily brian
dang bad luck for you buddy using that umbrella indoors
I can't thank you enough, oooh man you helped me a lot .. THANK YOU SO SO SO MUCH
Calling math cool is like calling Monday, Friday. It doesn't make it any better.
You have the greatest math help videos ever i wish i discovered you earlier!
I wish I had a teacher like this. Most teachers these days make math so boring
O.o as soon as he said it looks like a rainy day huh? it started raining outside... wow.
Thank you so much this is extremely helpful and will definitley help me on my test :)
Thanks. Hah but now my math teacher will be confused why I didn't use my class method
Yes i agree the umbrella mode is easier and better understanding in what you are doing in your work.
why couldnt my teacher make it this simple. oh my gosh!!! thank you!!!
Not gonna lie, every time he opened the umbrella it kinda startled me.
This really helped a lot I like his teaching style and I like the numbers he used
O.O what kind of witch-craft is this? You sir have a magic umbrella.
why are all the tutorials on youtube better than my actual teachers?
I normally really good at math but this one is confusing :$
I normally really good at math but this one is confusing :$
How does this work if there is more then 3 terms?
Please help :3
lol i don't even have a math textbook for this year of Algebra...
THANK YOUU SOOOOOOO MUCHHHH!!!!!!!!! OMG YOU ARE MY HERO!!!!!!!!
Breath in and out and then please calm down or play in traffic
Words cannot describe... the thanks... I have... right now....
Oh man your answer is wrong...that’s not the way the teacher teach us
wow, thank you. you taught me a much easier way to factor :)
This worked solo well for me!!! I want this tutor. :)
what is a simple way to do this without the box
and stuff?
