First step multiply top and bottom by x2.
What's the next step?
Arnold F.
Do the algebra of the first step on your fraction and tell me what you get.

Yes, if you don't mind negative exponents you can factor that right away as the difference of 2 squares.

I'll finish this problem but outside of an actual lesson I wouldn't be able to to help you with the rest of your assignment.
You can factor 1 - x-2 as (1-x-1)(1+x-1). The lefts hand term will cancel with the denominator.
Depending on your teacher you could leave the answer as (1+x-1) or multiply by x/x to eliminate the negative exponent.
