Solution for i(3+2i)+(8-3i)(1+i)=0 equation:


Simplifying
i(3 + 2i) + (8 + -3i)(1 + i) = 0
(3 * i + 2i * i) + (8 + -3i)(1 + i) = 0
(3i + 2i2) + (8 + -3i)(1 + i) = 0

Multiply (8 + -3i) * (1 + i)
3i + 2i2 + (8(1 + i) + -3i * (1 + i)) = 0
3i + 2i2 + ((1 * 8 + i * 8) + -3i * (1 + i)) = 0
3i + 2i2 + ((8 + 8i) + -3i * (1 + i)) = 0
3i + 2i2 + (8 + 8i + (1 * -3i + i * -3i)) = 0
3i + 2i2 + (8 + 8i + (-3i + -3i2)) = 0

Combine like terms: 8i + -3i = 5i
3i + 2i2 + (8 + 5i + -3i2) = 0

Reorder the terms:
8 + 3i + 5i + 2i2 + -3i2 = 0

Combine like terms: 3i + 5i = 8i
8 + 8i + 2i2 + -3i2 = 0

Combine like terms: 2i2 + -3i2 = -1i2
8 + 8i + -1i2 = 0

Solving
8 + 8i + -1i2 = 0
