I can't seem to get the right answer for this question and was wondering if i could get some help? x^{2}-4/x-3 X 12-4x/x+2

Without bracketing symbols, I am making an educated guess you are given to simplify: $\displaystyle \frac{x^2-4}{x-3}\cdot \frac{12-4x}{x+2}$ First step: factor all numerators and denominators. What do you get?
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
I agree with your result, which I would write as 4(2 - x).
thank you so much!
