(8 + 12x + 4x2 + 2x2 + x3) = x3 + 8

Combine like terms: 4x2 + 2x2 = 6x2
(8 + 12x + 6x2 + x3) = x3 + 8

Reorder the terms:
8 + 12x + 6x2 + x3 = 8 + x3

Add '-8' to each side of the equation.
8 + 12x + 6x2 + -8 + x3 = 8 + -8 + x3

Reorder the terms:
8 + -8 + 12x + 6x2 + x3 = 8 + -8 + x3

Combine like terms: 8 + -8 = 0
0 + 12x + 6x2 + x3 = 8 + -8 + x3
12x + 6x2 + x3 = 8 + -8 + x3

Combine like terms: 8 + -8 = 0
12x + 6x2 + x3 = 0 + x3
12x + 6x2 + x3 = x3

Add '-1x3' to each side of the equation.
12x + 6x2 + x3 + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
12x + 6x2 + 0 = x3 + -1x3
12x + 6x2 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
12x + 6x2 = 0

Solving
12x + 6x2 = 0
