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.

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?

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

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

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

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

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

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

[sharifayesh]

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

[Dr-Dre]

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