(x-2)(-1x-1)=0

Solution for (x-2)(-1x-1)=0 equation:

Simplifying
(x + -2)(-1x + -1) = 0

Reorder the terms:
(-2 + x)(-1x + -1) = 0

Reorder the terms:
(-2 + x)(-1 + -1x) = 0

Multiply (-2 + x) * (-1 + -1x)
(-2(-1 + -1x) + x(-1 + -1x)) = 0
((-1 * -2 + -1x * -2) + x(-1 + -1x)) = 0
((2 + 2x) + x(-1 + -1x)) = 0
(2 + 2x + (-1 * x + -1x * x)) = 0
(2 + 2x + (-1x + -1x2)) = 0

Combine like terms: 2x + -1x = 1x
(2 + 1x + -1x2) = 0

Solving
2 + 1x + -1x2 = 0
