Start by making common denominators in both top and bottom of the fraction. You follow?
yup i did do that. the answer i got was x^3/(-x^3+2x^2-x-1) but the answer sheet says its x^3/(-x^3+2x^2-1)
Thank you for using brackets, but this is still very hard to read...
Is it ?
If so, start by making some common denominators
yup i've got it now. thanks! :)
