Adding and Subtracting Rational Expressions With The Same Denominators

This algebra video tutorial explains how to add and subtract rational expressions with like denominators. You simply need to add or subtract the numerators of the fractions. Don't forget to distribute the negative sign. This video contains plenty of examples and practice problems.

The voice is so relaxing unlike those other videos that sound like broken RUBIX cubes

[pumkinmathy]

This dude is literally one of the best teacher's that have thought my dumb ass brain.

[verynormalweirdo]

Thank you so much! i was really struggling with this lesson but you explained it in a way that makes it seem easy to do

[georgesadler]

MR. Organic Chemistry Tutor, thank you for another helpful video/lecture Adding and Subtracting Rational Expressions with the same Denominators in Algebra/College Algebra. These examples are similar to adding numbers with the same denominators.

dawg like wtf I understood every single thing this guy said while my teacher literally confused the living shit out of me

[sebastianmorales]

Thank you for this explanation, May God Bless You and His Peace Be Upon You Always!

[mintyychoco]

Am I the only one that's falling inlove with the voice? ;-;

[pilotjdb]

Bro u made it so simple while my school made me so confused.

[JamesMiller-fpvn]

Could you please do a video on equilibrium

[axjd]

Theres gotta be faster than that, he solve it so fast i cant even keep up 💀

[lidinasinalimbo]

Thank you so much now i know how subtract it

[kikinggwapi]

I don't get it why u need to distribute the - sign

[AstelAstarel]

my teacher sent me this because i failed the test

[jzkhhdh]

In quedtion 3. how did the answer become 3(4x-1)
———-
X+2

[nyuhnerysmexecutioner]

jesus this is so simple compare to the unlike denominators which is 20x harder than this XD

[ariellemariepatinogloria]

Well, the numerator has x² something, what to do with it?

[mrbeltr]

So what happens if you have different exponents ?! Do you just add or keep the same ?

[omes]

Can you please explain how 7 (x+1) happened?

[Alex-Aries]

what if the first part of the given is two letters with no numbers?

[tevinfitzgerald]

how did you get positive 12 when the expression started out with a negative 12?
