help please i lost at 9:04 to 9:20 how did he do that
@@sanopann1896 hi! Umm in the equation (x-2) the "A" is x and "B" is -2. Just substitute those values on the formula (A-B)(A^2+AB+B^2)
Burh thank you so much for timestamp it helps me so much better to review. Thank you a lot! HAVE A GOOD DAY ALWAYS
Thanks for parting the video, I don’t have to watch the whole video
Thanks a loooooooot
The whole problem for a lot of people to grasp is factoring. Once they see how easy it is, less stress.
Step 1: mult A and C
Step 2: break apart Bx such that the sum = Bx
but the product = AC (edited)
Step 3: Split down middle with parentheses
Step 4: Divide out factors such the factored
pairs left over are equivalent
Step 5: 1 of the left over factored pairs is one of
the solutions
Step 6: The other solution is found by
combining what was divided out
This method works for pretty much every ax^2+bx+c(standard form) equation and I have found that usually the only time it doesn’t work is when it is nonfactorable. Hope this helps!
@@mpav1408that is only good if it's a trinomial, there are other factoring methods like synthetic division, factoring when a is not 1, factoring when a is 1, factoring by gcf, factoring by grouping, difference of two squares, difference of two cubes, sum of cubes
You are a LIFE SAVER! Believe it or not, this video is going to keep me in college!!!! THANK YOU!
Glad to help.
+The Organic Chemistry Tutor your the best
College?? What?? I took this at 8th grade I guess
@@sourayeaturaye2498 yeah this is also used in College Algebra.
IM IN MIDDLE SCHOOL AND I HAVE TO LEARN THIS UR IN COLLEGE!!!!!!!!!!!!!!!!!!!!! W.T.F.!!!!!!!!!
I think my brain is going to explode
same here
same, we got a test tomorrow and I'm crying while watching this.
@@markeulee8314 SAME OMG
I have a quiz tomorrow don't know what tf im doing
it's a headfuck 95% of students will never use but you get failed if you dont get it'
thank god there is the internet for when your professors try to over complicate things with shit methods
Syndikit amen to that 😂👏🏽👏🏽👏🏽
at least your professor tries to teach you. Mines tenured and about to retire and doesn't give a f*ck.
God* always big letter G
@@joshuamajano8358 not that,
I was wearing earphones max. volume when he cleared his throat
lol I was too!!!!!!!!!!!!!!!!!!!!!!!!
RIP💀
LOLOLOL😅😅😂😅😅😂😅😂😂😅😂😅😅😂😂😅💫
EwwwwwwwwwwwwwwwWWWW!!!! *shudder*
Timestamp pls!! Save us from the same faith of pain and suffering.
Stop reading comments and do your math
:c You got me
Just a sec
ok
I'll do it later
Make me!!! >:(
Jk
POV:you have to go back to school but you've been cheating on everything and you have a test tomorrow morning
Dear Professor I am very thankful for your video I've learned a lot again THANK YOU SO MUCH MORE POWER TO YOU AND GOD BLESS YOU.
i still dont get it
This man has saved millions. He deserves the title of hero.
You are a W. You're there for me for my Math and for my Chem AP and everyone in my school who knows of your existence are basically passing all their classes with a +110% average. You're a legend.
God bless you sir, you help millions of students like me all around the globe
0:23 "foy nine"
don’t be rude LOL
Foy nine
Change speed to 0.5 and then skip to 9:40 of this video :)
lol
god bless you
omg
Aahahahahah
Lol😂😂😂
you're the reason why i answered my chemistry and mathematics man, you're the best!!!
only @ 6:30 rn but this little hour and a half is gonna pay off cs ya girl got her ALG 2 midterm tmr on this & we just learned it appreciate you for this you a real one 💪🏽
omg I love that shortcut you did, instead of you writing out the negative exponent you just put it on the bottom to make it positive
my ear is bleeding because of the way he clears his throat and i have earphones and the volume is almost maxed... Why... you okay dude?
but the whole video is 100% useful man... Especially in this pandemic where the internet is our best partner in finding answers. Thanks bro appreciate it
Learning journey the pandemic is a tough task! The youtube way of learning helps a ton because students can pause and play the video at varying speeds!

Fr, it hurt me so much lmao
I'm a high school freshman and your videos have saved me and my friend's grades . . . thank you so much
I've been watching your videos for 2 years now, and it really helped me with my math. Btw, your voice is so therapeutic!
Thank you! You saved my life for becoming a failure in math, Whoever needs help in their math you need to watch his video because it is more clear than my module
I love how therapeutic your voice is. this works for me.thankyou
Whenever I'm bored I watch these vids and learn something instead of wasting time on other things.
You're wasting your time, hadn't you learn this on high school?? 🤨
cant relate
@@xdbeats790 Oooh! That was a nine-degree burn on that one-
pls do my hw

Remember that if you have trouble factorising quadratics. You can just use the quadratic formula to find the x intercepts and use it to factorise the expression.
I have a unit test tomorrow and none of this makes any sense , my head is gonna explode
i just needed a quick review but thnx for an hour n a half of content dude
I'm so thankful for your tutoring services i hope you will stay for a long time here on youtube :)
These were the exact SAT problems I BOMBED on. Now I know how to solve them. Thank you
9:45 my dude started a lawnmower😆
*pauses video at **50:15*
*Spends ten minutes working out problem, and gets frustrated at the weirdness...*
*finds out...*
There's a typo and the video was posted without any annotation on mistakes.
I feel you fam, same happen to me

Extra practice never hurt
Thank You Professor for your video, Rational Expressions , Adding, Subtracting, Multiplying, Dividing, Simplifying Complex Fractions. I've struggled with College Algebra, and had to take the class again this summer. I've watched the entire video, and wrote down and followed every problem on that video, as I took notes on the different techniques you used. Now I'm confident that I'll pass the College Algebra course when I retake it this summer. I'll bookmark your website, so I can refer to it and will decide if I want to a membership. Thank You very much. Joseph Lang
This guy has helped me through college algebra homework. I would get 80-100 percent on all of my assignments.
My nerves failed me on the the computerized test, with receiving something like a 13 percent. But since I had to show my work, on paper, I ended up getting a high F 😂. Two points away from passing.
That was my first exam.
As for my second, idk what I got.
I love the way you say 49! Btw thanks for the great content! Your videos helped me pass my last class 👌🏽
Foy nine
For 5:55 you can also multiply by the conjugate and solve to get 1/ -1 = -1 but its a bit longer :)
Awesome video it's helping me in my precal 11
Your videos are keeping me alive in College. Thank you Sir.
Hey you good?
I just added all the exponents. Then did the simplified multiplication on top and bottom. Simplified and came up with the same answer.
THANK YOU SO MUCH, SIR! YOUR EXPLANATION IS THE BEST !!
Got a math test on this soon. One of my online friends sent it to. This video could be a lifesaver
Thank you soo much. I really learned a lot, hopefully I do well in this math class.

@@mathfullyexplained dont spread your channel on others, that is just rude.
very effective, good teaching, period.🗽
this is so helpful for people like me who have a math teacher that can't teach.
This is super helpful!! Thanks
You made my brain work very fast. Now I'm happy but I have headache as well. Anyway I appreciate your effort
I fell in love with that man as soon as he became a better teacher than mine ❤️🔥
Thank you so much your video is better than most of the other videos and I can actually follow these difficult problems.
Same here.
Thank you for your lesson
I'm writing maths tomorrow and I needed this
Thanks for your videos!!
Thank you for being so informative

YOU SAVED MY LIFE WITH UR VIDS my teacher is very confusing and you explained in a very good way thank you so much
I enjoyed your videos very straight forward for me lol
BIg thanks to you sir I really learn a lot with this 1 hour video
you videos are really good!
When i got into high school the teachers were surprized when i said this wasn’t taught in grade school

@@mathfullyexplained I checked it out and u dont explain it that well as this guy. i got full marks on my test because of this guy
@@Gamingeek143 each of my videos on a unit has many examples that you can follow. More practice. I find it hard to explain rational expressions in 1.5 hours. Very very important unit in algebra.
@@mathfullyexplained Look this guy is really help full to me. Im not a hater but everyone understands differently right?. As this guy explains I find it really help full but as u explain i dont find it help full. but im sure you are doing an amazing job on your channel. I just said it wasnt help full thats it. Keep up your good work on your channel and have a great day! ✌✌
You are too good !!!! I'm too slow🐌
When the only factor in the numerator that might match with the denominator is (x+4) you should try it first when factoring the denominator to (x+4)(x-1).
his writing has gotten so much better over 6 years loool
That was a great one stuff bro.Thanxs

I have exams tomorrow I'll come back here tomorrow for the results. I hope to do welll. Thank you for this!
you are so good at Rationals and factoring..i what to ask what is really the step by step in factoring and and in fractional expression ? please show me how really is the step by step process in dealing with this matter. :) and also the technique in factoring numbers.

Lots of judgy little sh*ts in the comments section of this video. We get it guys, you are great students who learned this in 8th grade, congrats! Now let the rest of us relearn this stuff so we can pass college algebra.
at 53:20,why cant we use minus sign throughout the whole question?why do u need to change it to plus?
Best channel
wow espectacular expolicacion de loqiue es una derivada cuantica
thanks i almost perfected the exam but the essay and multiple choice 67/75

Probably the most tedious section of algebra 2.... Jesus.
Yes ir is. A lot of work. Easy to make a mistake.
I have been studying Algebra via UA-cam for several weeks, this is the first thing I have hit a mental block on.
I dunno, I thought Geometry proofs were worse.
In my opinion, the most difficult is adding and subtracting rational expressions with unlike denominators. Solving them are painfully long and tedious
@@Ben-fy3dl seriously though, I have to memorize like most of these and now my brain hurts
Still second year high school, this really helped me. Thank you :3
40:05 i dont get why he changed the negative sign to a positive pls help me ❗️

Hahah not too many teachers are great with tech so I can imagine that's the case. Learning on UA-cam is a life saver!

At 42:00, should be 2-y become -y+2/-1= y-2? then retain minus sign before 3y^2?
gracias, maestro
My hero 👍👍😊
19:41
Is it just me or the expression listed above;
*2x+1/2(x-5)* Can further be factored?
*2•x+1/2•x-10*
Giving us *1/-10?*
Very good great

@@mathfullyexplained try my channel where I explain spamming the comment section to plug your channel is in bad taste.
@@bearmanpig1568 just giving people an option to view my units with videos done in a sequence. I though the more explanations could lead to a better understanding.
Numbers bless you man
Is there another way to do it if the first coefficient isn’t a 1 instead of multiplying the first and last number
THANKS
this dude is my GOAT
Thanks bro
