(1 - x)² (x + 1)² [- (1 - x) ] ³
(1 - x)^5 (x + 1)² (-1)³
- (1 - x)^5 (x + 1)²

First off, (1 - x) = -(x - 1), so (1 - x)^2 = (x - 1)^2. So we can rewrite this as

(x + 1)^2(x - 1)^5

and that would be considered simplified. You can't cancel out (x + 1) with (x - 1) or anything like that. However, the product of (x + 1) and (x - 1) is (x^2 - 1), so you could further rewrite the product as (x^2 - 1)^2(x - 1)^3, but it's not more simplified that way.

it look like you have to expand the equation however the

(1-x)(1-x)(x+1)(x+1)(x-1)(x-1)(x-1)

expand and rearrange
equation can be rewritten as below
=> (1-x)(x-1) (x+1)(x-1)(x+1)(x-1) (1-x)

=> (x-1-x2+1)(x2-x+x-1)(x2-x+x-1) (1-x)
=> (x-x2)(1-x) (x2-1)(x2-1)
=>(2x-2x2)(x4-2x2+1)
=>2x^5-4x^3+2x-2x^6+4x^4-2x^2
=>2(x^5-2x^3+x-x^6+2x^4-x^2)
=>2x(x^4-2x^2+1-x^5+2x^3-x)
=>2x(x^4-2x^2-x^5+2x^3-x+1)

i hope i didnt miss out any step
