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

Reorder the terms:
(-1 + -2i + -1x + (-2i + -2ix + -4i2) + x(1 + 2i + x)) = 0
(-1 + -2i + -1x + (-2i + -2ix + -4i2) + x(1 + 2i + x)) = 0
(-1 + -2i + -1x + -2i + -2ix + -4i2 + (1 * x + 2i * x + x * x)) = 0

Reorder the terms:
(-1 + -2i + -1x + -2i + -2ix + -4i2 + (2ix + 1x + x2)) = 0
(-1 + -2i + -1x + -2i + -2ix + -4i2 + (2ix + 1x + x2)) = 0
