Solution for =(3+4i)(3+4i) equation:


Simplifying
0 = (3 + 4i)(3 + 4i)

Multiply (3 + 4i) * (3 + 4i)
0 = (3(3 + 4i) + 4i * (3 + 4i))
0 = ((3 * 3 + 4i * 3) + 4i * (3 + 4i))
0 = ((9 + 12i) + 4i * (3 + 4i))
0 = (9 + 12i + (3 * 4i + 4i * 4i))
0 = (9 + 12i + (12i + 16i2))

Combine like terms: 12i + 12i = 24i
0 = (9 + 24i + 16i2)

Solving
0 = 9 + 24i + 16i2

Solving for variable 'i'.

Combine like terms: 0 + -9 = -9
-9 + -24i + -16i2 = 9 + 24i + 16i2 + -9 + -24i + -16i2

Reorder the terms:
-9 + -24i + -16i2 = 9 + -9 + 24i + -24i + 16i2 + -16i2

Combine like terms: 9 + -9 = 0
-9 + -24i + -16i2 = 0 + 24i + -24i + 16i2 + -16i2
-9 + -24i + -16i2 = 24i + -24i + 16i2 + -16i2

Combine like terms: 24i + -24i = 0
-9 + -24i + -16i2 = 0 + 16i2 + -16i2
-9 + -24i + -16i2 = 16i2 + -16i2

Combine like terms: 16i2 + -16i2 = 0
-9 + -24i + -16i2 = 0

Factor out the Greatest Common Factor (GCF), '-1'.
-1(9 + 24i + 16i2) = 0

Factor a trinomial.
-1((3 + 4i)(3 + 4i)) = 0

Ignore the factor -1.

Subproblem 1
