Solution for y=[x-(-2+i)][x-(-2-i)] equation: 


Simplifying
y = [x + -1(-2 + i)][x + -1(-2 + -1i)]
y = [x + (-2 * -1 + i * -1)][x + -1(-2 + -1i)]
y = [x + (2 + -1i)][x + -1(-2 + -1i)]

Reorder the terms:
y = [2 + -1i + x][x + -1(-2 + -1i)]
y = [2 + -1i + x][x + (-2 * -1 + -1i * -1)]
y = [2 + -1i + x][x + (2 + 1i)]

Reorder the terms:
y = [2 + -1i + x][2 + 1i + x]

Multiply [2 + -1i + x] * [2 + 1i + x]
y = [2[2 + 1i + x] + -1i * [2 + 1i + x] + x[2 + 1i + x]]
y = [[2 * 2 + 1i * 2 + x * 2] + -1i * [2 + 1i + x] + x[2 + 1i + x]]
y = [[4 + 2i + 2x] + -1i * [2 + 1i + x] + x[2 + 1i + x]]
y = [4 + 2i + 2x + [2 * -1i + 1i * -1i + x * -1i] + x[2 + 1i + x]]

Reorder the terms:
y = [4 + 2i + 2x + [-2i + -1ix + -1i2] + x[2 + 1i + x]]
y = [4 + 2i + 2x + [-2i + -1ix + -1i2] + x[2 + 1i + x]]
y = [4 + 2i + 2x + -2i + -1ix + -1i2 + [2 * x + 1i * x + x * x]]

Reorder the terms:
y = [4 + 2i + 2x + -2i + -1ix + -1i2 + [1ix + 2x + x2]]
y = [4 + 2i + 2x + -2i + -1ix + -1i2 + [1ix + 2x + x2]]

Reorder the terms:
y = [4 + 2i + -2i + -1ix + 1ix + -1i2 + 2x + 2x + x2]

Combine like terms: 2i + -2i = 0
y = [4 + 0 + -1ix + 1ix + -1i2 + 2x + 2x + x2]
y = [4 + -1ix + 1ix + -1i2 + 2x + 2x + x2]

Combine like terms: -1ix + 1ix = 0
y = [4 + 0 + -1i2 + 2x + 2x + x2]
y = [4 + -1i2 + 2x + 2x + x2]

Combine like terms: 2x + 2x = 4x
y = [4 + -1i2 + 4x + x2]

Solving
y = 4 + -1i2 + 4x + x2

Solving for variable 'y'.

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

Simplifying
y = 4 + -1i2 + 4x + x2
