Thread: 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

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



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!
