Dividing rational expressions

Learn how to divide rational expressions. A rational expression is an expression in the form of a fraction, usually having variable(s) in the denominator. Recall that to divide by a fraction, we multiply by the reciprocal of the fraction. The same rule applies when we want to divide by a rational function.
Given two rational expressions, where one is dividing the other. We first turn the divisor rational expression upside down and change the division sign to multiplication sign. Next, we factor all the polynomials and then cancel out all the common factors between the numerator and the denominator. We then multiply the remaining numerators together and the remaining denominators together. The result is the simplified quotient of the two rational expressions.

The answer is actually (x-4)(x+3) not (x-4)(x+1)

[@thetexan1011]

you are literally the only person that can explain this stuff to me, I feel like imma be back here many times

[@layla._.southsparrow]

Your vids are a savior omg 🙏 you go at a good speed and dont talk like your dead inside (like most yt math vids LOL) and it really makes a difference

[@Workoutpitbull]

Thank You Mr .,Mclogan Really struggled till watching this

[@atousanariman5139]

I dont know if I’m wrong but when you said two numbers multiply to equal 12 but add to equal -1 wouldn’t that be -4 and 3 not -4 and 1?

[@pitoumil7447]

yeah i notice that too

[@kevinsheppard2312]

He corrected himself at the end. Caught me off guard lol.

[@user-ns1zw]

Same i though I was trippin

[@cypherknot]

He got that one wrong. He often gets something wrong.

[@karmablack1725]

Yea thats what i got

[@itsjustruba2653]

Thank you, this really helped.

[@thatonekid1190]

This taught me more than my teacher did. Mostly because I'm on my and learning math at the same time.

[@vaned7496]

ur the best

[@emymaddox6671]

Awesome I love this!! Thank you Sir!! :DD

[@atousanariman5139]

Oh never mind I saw that you fixed it later in the video

[@uNknownrMx]

Love you bro!

[@sharifayesh1667]

bro had me second guessing my life when he missed the x+3

[@lifewithjade2352]

Your amazing

you scared me at that (x-4)(x-1)

[@Swindler4]

What class is this typically taught in? Algebra 1 or Algebra 2?

[@why-vu9jd]

i got it in 2

grade 10 math here in canada

[@mattrivers2720]

2

[@allaboutcharrr]

Algebra 2 and Math College Readiness as well

[@Dr-Dre]

Ok how do I do that if one of them is “3x+5”? Can I? Cuz I need to.

[@brianmclogan]

Same process?

[@Urawizardharryy]

I don't understand why can you divide 2x-1 from both fractions

[@irwandasaputra9315]

(x-2)(x+1):(2x-1)(x-2)-(x-4)(x+3):(2x-1)(x+3)
(x+1):(2x-1)-(x-4)(2x-1)
5:(2x-1)

[@irwandasaputra9315]

(x-2)(x-1):(2x-1)(x-2)/(x-4)(x+3):(2x-1)(x+3)
(x-1):(2x-1)/(x-4):(2x-1)
(x-1):(x-4)

[@chonch4life851]

Not explaining it at all, too fast

[@brianmclogan]

Sorry
