Solution for f(x)=(200-2x)(120+2x) equation: 


Simplifying
f(x) = (200 + -2x)(120 + 2x)

Multiply f * x
fx = (200 + -2x)(120 + 2x)

Multiply (200 + -2x) * (120 + 2x)
fx = (200(120 + 2x) + -2x * (120 + 2x))
fx = ((120 * 200 + 2x * 200) + -2x * (120 + 2x))
fx = ((24000 + 400x) + -2x * (120 + 2x))
fx = (24000 + 400x + (120 * -2x + 2x * -2x))
fx = (24000 + 400x + (-240x + -4x2))

Combine like terms: 400x + -240x = 160x
fx = (24000 + 160x + -4x2)
