I'm 7 I just watched this to look cool in front of my friends
😂
Lol
HELP-
Wow😭
lol, awwwe
Are the videos from 2006 REALLY helping?
lmfao
HAHAHHAHAA LOL ALWAYS THE AD FOR MATH VIDEOS
@@LicXisadopted same
nope i laughed when i saw this comment im so tired of that Ad
Yes
I'm just trying to solve some like problems, and your videos are the best I've seen so far. Just note, that explaining math is one of your strong points. Thank you.
Yeah! He is our real math teacher who can explain us every detail than our original teachers!
The expression: "Keep, Change and Flip" can also be called the ' reciprocal'
KCF
Or inverse
or kfc?
@@samn2337 q1
@@seanoreilly9950 keep flip change is technically just the same thing, so yes
All these 8th graders but I'm studying to graduate XD
Me Too :) & I am 27
I’m 14 this is hard lol, doing further maths
im studying this for the second time bc i rly dont wanna repeat algebra 1 in hs-- woo... placement tests ;w;
Im at the 8th grade 12 years old.And i need to understand this while at home cause of freaking corona🤦
@Lancekledsen Encallado HAHAHAHAH
ah yes, my mortal enemy from 8th grade, I'm relearning it for alg II :(
How’s life now?
I am 26 and watching this to help me with my college algebra exam today. To all the kids here - please do well while you’re in high school so you don’t have to study at your full time job 😅
God I’m in the exact same boat. I was such a dumbass focusing on being the class clown instead of trying to learn everything, now here I am making major life changes, going back to college at 26 with the end goal of getting my doctorates, as a single dad with 3 kids 😂. Wish me luck
@@Dr_Infantryw also cool pfp
I’m studying for college to get a full time job 😭🙌
I have an assessment in a few days. I had to go back to the basic to learn terminology and function. The first couple of days, I was so confused. Only by God's grace, I am still pushing. 😅
your examples work out very conveniently
You are really a great teacher, thank you so much, I'm recovering in a few days years of non understood topics
MR. Organic Chemistry Tutor, thank you for another monster video/lecture on Dividing Rational Expressions in Algebra Two. I really enjoyed this topic on rational expressions.
The best teacher on the internet
This channel is a lifesaver.
thank you so much for all of your helpful videos.
Bruh this guy has been helping me since 4th grade thank you bro im in 8th grade now
you are now my math teacher
I'm in grade 8 and this was our topic and I'm stressed
Same
Sameee i fucked up bro
Same
Makinig ka sa teacher mo
same !!!!!!!!!! i’m in grade 1 !!! and this was only my topic cause i’m superior mensan !!! i’m not stressed though, very very easy !
literally have an exam in 15 minutes YOU'RE SAVING MY LIFE
How’d it go
My teacher sucks in explaining that's why I came here i saw this video and directly subscribed
I'm year 8 too
watching this morning of my test for review, thank you so much
Thank you!! Very useful.
You are really great appreciate it sooooo muchhh thannkkk youuu man
THANK YOU!! im in 7th grade, i have like 6 chapters for my final, and i completely forgot all the material. ive been binge watching your videos. you save me so much time and make it easy to understand! thank you so much. -coming from a person whose shit at math
*Who’s
You're great! 💓
Thank you for this God's product, now I can easily understand all the topics
These really hard to understand and the alphabet I can't understand it a little bit but still thankful to this video..It help me to know how to solve the expression and so I can now answer my math subject without using apps
Thank you for the video😄
Completely forgot about this so now I'm relearning it for Algebra II
Thank you 👍
believe it or not i've watched 29 videos of yours today only...and imma keep going.
I feel this
Thanks for this video, I'm a Grade 8 student and this will be our next lesson...
I owe you so much bro im gonna pass math cuz of you
Im in grade 8 i need an binomial example of division
Quick question, on the first equation, doesn’t the top (over 1) also need to be multiplied by 4 before the expressions can become a whole?
Best of all times
It helps a lottttttt
In 6:25 why did he factor out the 6(x^2+4) using the cube identity even though it is not raised to 3 or cube rather.
2:21 how come we didn't cancel the (x+3) w the (x+3)? there are the same
because they are both in the denominator u cant cancle them unless they were upbove wach other or there is multiplication sign between two expressions and one is denominator and the other one Is numerator in the other expression ( hope that helped english is not my first language )
I get it, its just a lot of work lol
0:00 Focus on dividing Rational Expression and determine the excluded value
11:24 Put the denominator on the outside and the numerator on the inside
thank you sir
In the last example could we further factor 4x^2+8x+26 into x^2+2x+7?
lol no
THANKS IM NOW CONFIDENT DOING MY EXAM
Ur amazing
Wait so what is the point of Excluding Values?
This is crazy I didn’t know you learned this so early I guess I forget, I’m in my second year of college and have an exam tomorrow
Where u get the three from
howd you get x2-2x+4????
How do u get a 2 for B in the sum of perfect cubes when the 8 is the B?
8 isn't B is B cubed, so if you use a cube root on the 8 its 2
Am I the only high schooler who's JUST learning this and being anxious that there are a bunch of middle schoolers already learning this 😭😭
same bro
i just got into highschool and we learned this in 8th grade 😭
@@caily9316 Wtf ☠️ what math class did you take in 8th?
Any one come to the coments to stop doing homework?
Reviewing for a PT exam.
At 6:32 how did he get 2(x-5)/3? what did he simplify or divide to get there? Somebody please explain!? Whats wrong with the volume? It goes up and down. I can barely hear!
Hi
I don't get the subtracting part on 10:01
2:11 in this case, why didnt you just do x + 5^2?
9:14 never seen this before. i would've factored the top and reduced it. but the long division does look cool
Only here beacause i was late at the lesson, but thanks to this guy i will be able to answer at our quiz 💀🙏
at 11:50 why did he add the extra 0x? I'm not following. Everything else in this video did make sense though
this is helping me so much in algebra 2 bc im just staring at someone’s back fat the whole time
they made me sit behind the obese person in school and i already have shitty vision so that doesnt make it any better
That all about Diving Rational Algebraic Expressions
I got perfect on the first test i wanna keep being perfect to rub it off on my classmates >:) also i wasn't there for the lesson so i need this XD
Its actually easy Just gotta learn first how to factor and so on :))
There are some reciprocals added for dividing fractions
Just wanna ask where did you get the two? At the A³ + B=(A+B) ....
Part?
Multiplying a trinomial
It's the formula
He got the two by by finding cube root of 8
Why does the x+3 didn't cancelled
Thank you! I am studying algebra all by myself. Which grade is this because I am in Grade 7?
8th
Grade 7-8 i think
I believe it's usually highschool algebra stuff
keep it up ian!
@@InChristIDelight thank you
How can you use the Sum of perfect cubes with x^3+8 when 8 doesn’t have an exponent of 3?
8=2^3
why did you take out a negative when multiplying at 9:37 ?
I agree
because its division like this
Ex.
9 L (Upside down sorry)
3
9 L27
- (this!)
he made the 12 positive in (8x²-12x ) because there was a negative outside of the parentheses,, therefore u have to flip both signs making 8x² into -8x² and -12 into positive 12
i hope that maybe helped?😭
It's so easy when u not complain
I’m literally just doing this in grade 10 wtf are you people on
I feel ur pain
Exactly like they making me feel dumb
Bruh I'm a 7 grader and I could feel like my brain's about to explode
Let's do this 🥊🥊💯🤧
Bro where did go the x2+8x+
Why did you add a 0x²?
I'm confused
@@vincent_gwapo on the last problem he added 0x² To the dividend even when 0x² is not even on the problem/equation
@@vincent_gwapo you can see that the first equation your dividing a trinomial with a binomial but when he long divisioned its a polynomial with a binomial
Can you explain what you mean by excluded values and the reason behind why they are excluded, Thanks!
Did you ever figure it out
@@makenziemarr8221 Sorry no.
@@makenziemarr8221it is the non permissible values, the values in which X cannot equal, as it will result in you dividing by 0 which is not real.
Im crying while trying to understand the vid TT∆TT
same XD
thanks lil tecca
Bro i dont understand
Why can't we cancel (x+3) and (x+3) at 2:20?
You cannot cancel across, only diagonal and/or vertical. Since the two (x+3) are both in the numerator, you can write them as one and simply square it. It's just the same as (x+3)(x+3). I hope this helps.
@@michy_documents Okay, thank you.
You guys are learning this in 8th grade?? I'm in 10th just learning this at the end of the class!
0:00:00
how come after the fractions flipped I don't understand a thing anymore.
Our brains flipped upside down either that or were just slow af
any one hear filthy to try this example instead of feel free to try this example at 8:01 :]
the homie
I got u😃
I'm in grade 8 and I'm finding some solution for my pre assessment test :>>> So don't mind me HSHSHSHHS
i literally do not remember how to factor anything OSUFGHLDLYFOUFE i blame my slow processing and forgetful brain u-u
Why didn’t he Cancel X+3 with X+3 in the First Example?

jusq bukas na test
Hahahaha kami bukas
what about A to the 3rd - B to the 3rd? thanks for showing A cubed + B cubed(sorry my exponents won't work)
A to the third is equal to A cubed...
What done account said
I’m watching in 9th grade to help with Alg 2
Im 6th and im learning this-
First I Should master factoring polynomials so I can easily solve RAEs
Second example tho😭💀
im gonna explode
Most of the people here is just watching for there future math change my mind
IN SCHL: How did you?? Why??? What??
IN YT: ahhh okay.. alright... I seee...
thats meh XD
My brain hurts
oof my mind blown
Everyone being 8th graders while here I am a 7th... Whyyy 😭😭😭
Why do maths so difficult😔
