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

Multiply (2 + -1x) * (2 + -1x)
(2(2 + -1x) + -1x * (2 + -1x)) = -1
((2 * 2 + -1x * 2) + -1x * (2 + -1x)) = -1
((4 + -2x) + -1x * (2 + -1x)) = -1
(4 + -2x + (2 * -1x + -1x * -1x)) = -1
(4 + -2x + (-2x + 1x2)) = -1

Combine like terms: -2x + -2x = -4x
(4 + -4x + 1x2) = -1

Solving
4 + -4x + 1x2 = -1
