480 = ((132 + 12X) + X(11 + X))(-2 + X)
480 = (132 + 12X + (11 * X + X * X))(-2 + X)
480 = (132 + 12X + (11X + X2))(-2 + X)

Combine like terms: 12X + 11X = 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
