(-1-x)(1-x)=0

Solution for (-1-x)(1-x)=0 equation:

Simplifying
(-1 + -1x)(1 + -1x) = 0

Multiply (-1 + -1x) * (1 + -1x)
(-1(1 + -1x) + -1x * (1 + -1x)) = 0
((1 * -1 + -1x * -1) + -1x * (1 + -1x)) = 0
((-1 + 1x) + -1x * (1 + -1x)) = 0
(-1 + 1x + (1 * -1x + -1x * -1x)) = 0
(-1 + 1x + (-1x + 1x2)) = 0

Combine like terms: 1x + -1x = 0
(-1 + 0 + 1x2) = 0
(-1 + 1x2) = 0

Solving
-1 + 1x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1' to each side of the equation.
-1 + 1 + 1x2 = 0 + 1
