Question

Simplify:

Answer 1

Can you factor -1 from the numerator? Then change the order of the x and the number. What do you get?

Answer 2

I would get (x-1)/(x-1) which cancels out to 1 or -1.... I don't know which

Answer 3

First, you just factor -1 from the numerator.
Notice that if you multiply out the new numerator, you get back to what it was, so the factoring of -1 is correct. Ok so far?
