1. ## Simplify

I can't seem to get the right answer for this question and was wondering if i could get some help?

x2-4/x-3 X 12-4x/x+2

2. ## Re: Simplify

Without bracketing symbols, I am making an educated guess you are given to simplify:

$\frac{x^2-4}{x-3}\cdot \frac{12-4x}{x+2}$

First step: factor all numerators and denominators. What do you get?

3. ## Re: Simplify

i ended up with (x+2)(X-2) . -4(x-3) then cancelled common terms and was left with -4(x-2)

however the answer in my textbook is -4x^2+20x-6 / x-3

4. ## Re: Simplify

I agree with your result, which I would write as 4(2 - x).
