Do you mean:
- x / (x2 - 1)? If so, that's as simplified as you can get.
(- x / x2) - 1? If so, that simplifies to (-1/x) - 1.
(-x/x)2 - 1? If so, that simplifies to 0.
-(x/x)2 - 1? If so, that simplifies to -2.
Or perhaps that dash in the question is actually a hyphen, in which case:
x / (x2 - 1)? If so, that's also as simplified as you can get.
(x / x2) - 1? If so, that simplifies to (1/x) - 1.
(x/x)2 - 1? If so, that simplifies to 0.

Nope! It's (x+ 1) (x-1). :)
x^2(1 - x)(1 + x)
- ln ((x^2)-4)
Dividend: x3+4x2-9x-36 Divisor: x+3 Quotient: x2+x-12
