=(x^2-2i^2)(x-3)

Solution for =(x^2-2i^2)(x-3) equation:

Simplifying
0 = (x2 + -2i2)(x + -3)

Reorder the terms:
0 = (-2i2 + x2)(x + -3)

Reorder the terms:
0 = (-2i2 + x2)(-3 + x)

Multiply (-2i2 + x2) * (-3 + x)
0 = (-2i2 * (-3 + x) + x2(-3 + x))
0 = ((-3 * -2i2 + x * -2i2) + x2(-3 + x))
0 = ((6i2 + -2i2x) + x2(-3 + x))
0 = (6i2 + -2i2x + (-3 * x2 + x * x2))
0 = (6i2 + -2i2x + (-3x2 + x3))
0 = (6i2 + -2i2x + -3x2 + x3)

Solving
0 = 6i2 + -2i2x + -3x2 + x3

Solving for variable 'i'.

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

Add '-6i2' to each side of the equation.
0 + -6i2 = 6i2 + -2i2x + -3x2 + -6i2 + x3
Remove the zero:
-6i2 = 6i2 + -2i2x + -3x2 + -6i2 + x3

Reorder the terms:
-6i2 = 6i2 + -6i2 + -2i2x + -3x2 + x3

Combine like terms: 6i2 + -6i2 = 0
-6i2 = 0 + -2i2x + -3x2 + x3
-6i2 = -2i2x + -3x2 + x3

Add '2i2x' to each side of the equation.
-6i2 + 2i2x = -2i2x + -3x2 + 2i2x + x3

Reorder the terms:
-6i2 + 2i2x = -2i2x + 2i2x + -3x2 + x3

Combine like terms: -2i2x + 2i2x = 0
-6i2 + 2i2x = 0 + -3x2 + x3
-6i2 + 2i2x = -3x2 + x3

Reorder the terms:
-6i2 + 2i2x + 3x2 + -1x3 = -3x2 + 3x2 + x3 + -1x3

Combine like terms: -3x2 + 3x2 = 0
-6i2 + 2i2x + 3x2 + -1x3 = 0 + x3 + -1x3
-6i2 + 2i2x + 3x2 + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
-6i2 + 2i2x + 3x2 + -1x3 = 0
