(132 + 11x + (12 * x + x * x))(-2 + x) = 480
(132 + 11x + (12x + x2))(-2 + x) = 480

Combine like terms: 11x + 12x = 23x
(132 + 23x + x2)(-2 + x) = 480

Multiply (132 + 23x + x2) * (-2 + x)
(132(-2 + x) + 23x * (-2 + x) + x2(-2 + x)) = 480
((-2 * 132 + x * 132) + 23x * (-2 + x) + x2(-2 + x)) = 480
((-264 + 132x) + 23x * (-2 + x) + x2(-2 + x)) = 480
(-264 + 132x + (-2 * 23x + x * 23x) + x2(-2 + x)) = 480
(-264 + 132x + (-46x + 23x2) + x2(-2 + x)) = 480
(-264 + 132x + -46x + 23x2 + (-2 * x2 + x * x2)) = 480
(-264 + 132x + -46x + 23x2 + (-2x2 + x3)) = 480

Combine like terms: 132x + -46x = 86x
(-264 + 86x + 23x2 + -2x2 + x3) = 480
