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

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

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

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

Combine like terms: 23x2 + -2x2 = 21x2
480 = (-264 + 86x + 21x2 + x3)

Solving
480 = -264 + 86x + 21x2 + x3
