Simplifying
3.2 = (11 + -2x)(8.5 + -2x) * x

Reorder the terms for easier multiplication:
3.2 = x(11 + -2x)(8.5 + -2x)

Multiply (11 + -2x) * (8.5 + -2x)
3.2 = x(11(8.5 + -2x) + -2x * (8.5 + -2x))
3.2 = x((8.5 * 11 + -2x * 11) + -2x * (8.5 + -2x))
3.2 = x((93.5 + -22x) + -2x * (8.5 + -2x))
3.2 = x(93.5 + -22x + (8.5 * -2x + -2x * -2x))
3.2 = x(93.5 + -22x + (-17x + 4x2))

Combine like terms: -22x + -17x = -39x
3.2 = x(93.5 + -39x + 4x2)
3.2 = (93.5 * x + -39x * x + 4x2 * x)
3.2 = (93.5x + -39x2 + 4x3)
