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?

@@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
You were my first algebra tutor when I began A1 last winter. I remember when this video was difficult. 6 hrs a day for months and not I'm beginning calculus. Did your Power Rule of Integration this week asking with derivatives and limits.
All this to say thank you, my guy.
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 7 I just watched this to look cool in front of my friends
😂
Lol
HELP-
Wow😭
lol, awwwe
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
The best teacher on the internet
ah yes, my mortal enemy from 8th grade, I'm relearning it for alg II :(
How’s life now?
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.
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
This channel is a lifesaver.
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
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 !
your are a best teacher that i found in youtube
Bruh this guy has been helping me since 4th grade thank you bro im in 8th grade now
you are now my math teacher
literally have an exam in 15 minutes YOU'RE SAVING MY LIFE
How’d it go
Update on the exam?
My teacher sucks in explaining that's why I came here i saw this video and directly subscribed
I'm year 8 too
believe it or not i've watched 29 videos of yours today only...and imma keep going.
I feel this
Thank you for this God's product, now I can easily understand all the topics
watching this morning of my test for review, thank you so much
i seriously trust u with my life
I get it, its just a lot of work lol
Completely forgot about this so now I'm relearning it for Algebra II
Any one come to the coments to stop doing homework?
Reviewing for a PT exam.
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
Thank you 👍
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
You are really great appreciate it sooooo muchhh thannkkk youuu man
thank you so much for all of your helpful videos.
Im in grade 8 i need an binomial example of division
THANKS IM NOW CONFIDENT DOING MY EXAM
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 )
Thanks for this video, I'm a Grade 8 student and this will be our next lesson...
9:14 never seen this before. i would've factored the top and reduced it. but the long division does look cool
I owe you so much bro im gonna pass math cuz of you
Good video, nice explaination like my math teacher
Thank you!! Very useful.
Only here beacause i was late at the lesson, but thanks to this guy i will be able to answer at our quiz 💀🙏
Best of all times
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?
I don't get the subtracting part on 10:01
You're great! 💓
Thank you for the video😄
In the last example could we further factor 4x^2+8x+26 into x^2+2x+7?
lol no
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?😭
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
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!

My holy brother in Christ? What the fuck is this?
It's so easy when u not complain
Wait so what is the point of Excluding Values?
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
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.
It's been 4 years, but to answer your question, he did not use the sum of two cubes-rather he used the sum of two squares of (x²-4) which is equal to (x+2)(x-2). Additionally, the 4/6 is equal to 2/3.
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
at 11:50 why did he add the extra 0x? I'm not following. Everything else in this video did make sense though
Just as a placeholder for the long division format to work
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?
2:11 in this case, why didnt you just do x + 5^2?
Let's do this 🥊🥊💯🤧
Its actually easy Just gotta learn first how to factor and so on :))
0:00:00
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.
Im crying while trying to understand the vid TT∆TT
same XD
There are some reciprocals added for dividing fractions
thanks lil tecca
any one hear filthy to try this example instead of feel free to try this example at 8:01 :]
That all about Diving Rational Algebraic Expressions
I have an exam after 2 hours and this helped a lot you don't get it
You guys are learning this in 8th grade?? I'm in 10th just learning this at the end of the class!
thank you sir
Bro i dont understand
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
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
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.
6:41
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
Where u get the three from
I'm in grade 8 and I'm finding some solution for my pre assessment test :>>> So don't mind me HSHSHSHHS
Most of the people here is just watching for there future math change my mind
I’m watching in 9th grade to help with Alg 2
Why does the x+3 didn't cancelled
Im 6th and im learning this-
Second example tho😭💀
IN SCHL: How did you?? Why??? What??
IN YT: ahhh okay.. alright... I seee...
thats meh XD
howd you get x2-2x+4????
Ur amazing
I don't understand the 3rd excample??
Everyone being 8th graders while here I am a 7th... Whyyy 😭😭😭
First I Should master factoring polynomials so I can easily solve RAEs
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
welcome to Asia
Me realizing I can just cross multiply then flip it😐
Ikr ( TДT)
Bro where did go the x2+8x+
jusq bukas na test
Hahahaha kami bukas
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
IM FKN COOKED ON MY TEST THIS IS SO CONFUSING 💀💀💀
i literally do not remember how to factor anything OSUFGHLDLYFOUFE i blame my slow processing and forgetful brain u-u
It helps a lottttttt
i love eating at KCF
