Simplifying
7i(3 + -4i)(3 + 4i) = 0

Multiply (3 + -4i) * (3 + 4i)
7i(3(3 + 4i) + -4i * (3 + 4i)) = 0
7i((3 * 3 + 4i * 3) + -4i * (3 + 4i)) = 0
7i((9 + 12i) + -4i * (3 + 4i)) = 0
7i(9 + 12i + (3 * -4i + 4i * -4i)) = 0
7i(9 + 12i + (-12i + -16i2)) = 0

Combine like terms: 12i + -12i = 0
7i(9 + 0 + -16i2) = 0
7i(9 + -16i2) = 0
(9 * 7i + -16i2 * 7i) = 0
(63i + -112i3) = 0

Solving
63i + -112i3 = 0
