Solution for y=(x-3-4i)(x-3+4i) equation:


Simplifying
y = (x + -3 + -4i)(x + -3 + 4i)

Reorder the terms:
y = (-3 + -4i + x)(x + -3 + 4i)

Reorder the terms:
y = (-3 + -4i + x)(-3 + 4i + x)

Multiply (-3 + -4i + x) * (-3 + 4i + x)
y = (-3(-3 + 4i + x) + -4i * (-3 + 4i + x) + x(-3 + 4i + x))
y = ((-3 * -3 + 4i * -3 + x * -3) + -4i * (-3 + 4i + x) + x(-3 + 4i + x))
y = ((9 + -12i + -3x) + -4i * (-3 + 4i + x) + x(-3 + 4i + x))
y = (9 + -12i + -3x + (-3 * -4i + 4i * -4i + x * -4i) + x(-3 + 4i + x))

Reorder the terms:
y = (9 + -12i + -3x + (12i + -4ix + -16i2) + x(-3 + 4i + x))
y = (9 + -12i + -3x + (12i + -4ix + -16i2) + x(-3 + 4i + x))
y = (9 + -12i + -3x + 12i + -4ix + -16i2 + (-3 * x + 4i * x + x * x))

Reorder the terms:
y = (9 + -12i + -3x + 12i + -4ix + -16i2 + (4ix + -3x + x2))
y = (9 + -12i + -3x + 12i + -4ix + -16i2 + (4ix + -3x + x2))

Reorder the terms:
y = (9 + -12i + 12i + -4ix + 4ix + -16i2 + -3x + -3x + x2)

Combine like terms: -12i + 12i = 0
y = (9 + 0 + -4ix + 4ix + -16i2 + -3x + -3x + x2)
y = (9 + -4ix + 4ix + -16i2 + -3x + -3x + x2)

Combine like terms: -4ix + 4ix = 0
y = (9 + 0 + -16i2 + -3x + -3x + x2)
y = (9 + -16i2 + -3x + -3x + x2)

Combine like terms: -3x + -3x = -6x
y = (9 + -16i2 + -6x + x2)

Solving
y = 9 + -16i2 + -6x + x2

Solving for variable 'y'.

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

Simplifying
y = 9 + -16i2 + -6x + x2
