Solution for =(1-3i)x(-2+5i) equation:


Simplifying
0 = (1 + -3i) * x(-2 + 5i)

Reorder the terms for easier multiplication:
0 = x(1 + -3i)(-2 + 5i)

Multiply (1 + -3i) * (-2 + 5i)
0 = x(1(-2 + 5i) + -3i * (-2 + 5i))
0 = x((-2 * 1 + 5i * 1) + -3i * (-2 + 5i))
0 = x((-2 + 5i) + -3i * (-2 + 5i))
0 = x(-2 + 5i + (-2 * -3i + 5i * -3i))
0 = x(-2 + 5i + (6i + -15i2))

Combine like terms: 5i + 6i = 11i
0 = x(-2 + 11i + -15i2)
0 = (-2 * x + 11i * x + -15i2 * x)

Reorder the terms:
0 = (11ix + -15i2x + -2x)
0 = (11ix + -15i2x + -2x)

Solving
0 = 11ix + -15i2x + -2x

Solving for variable 'i'.
Remove the zero:
-11ix + 15i2x + 2x = 11ix + -15i2x + -2x + -11ix + 15i2x + 2x

Reorder the terms:
-11ix + 15i2x + 2x = 11ix + -11ix + -15i2x + 15i2x + -2x + 2x

Combine like terms: 11ix + -11ix = 0
-11ix + 15i2x + 2x = 0 + -15i2x + 15i2x + -2x + 2x
-11ix + 15i2x + 2x = -15i2x + 15i2x + -2x + 2x

Combine like terms: -15i2x + 15i2x = 0
-11ix + 15i2x + 2x = 0 + -2x + 2x
-11ix + 15i2x + 2x = -2x + 2x

Combine like terms: -2x + 2x = 0
-11ix + 15i2x + 2x = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-11i + 15i2 + 2) = 0
