Nope! It's (x+ 1) (x-1). :)
x^2(1 - x)(1 + x)
2(x - 7)(x - 1)
(x + 2)(x - 4)
x(x - 2)
1-Cos^(2)x = Sin^(2)x This is algebraically rearranged from the Trig. Identity. Sin^(2)x + Cos^(2)x = 1 Which in turn is based on the Pythagorean triangle.
I believe it is prime as you have written it. change the end to + 81 and it factors as (2x - 1)(x-9)(x+9)
x + 1
(x - 1)(x + 1)
x(x-1)
(x + 1)(x - 8)
x = 1
x = ? 42 = x squared minus x
-3
This expression factors as x -1 quantity squared.

(x + 3)(x - 1)(x + 1)
