Simplifying v(x) = (20 + -2x)(20 + -2x) * x Multiply v * x vx = (20 + -2x)(20 + -2x) * x Reorder the terms for easier multiplication: vx = x(20 + -2x)(20 + -2x) Multiply (20 + -2x) * (20 + -2x) vx = x(20(20 + -2x) + -2x * (20 + -2x)) vx = x((20 * 20 + -2x * 20) + -2x * (20 + -2x)) vx = x((400 + -40x) + -2x * (20 + -2x)) vx = x(400 + -40x + (20 * -2x + -2x * -2x)) vx = x(400 + -40x + (-40x + 4x2)) Combine like terms: -40x + -40x = -80x vx = x(400 + -80x + 4x2) vx = (400 * x + -80x * x + 4x2 * x) vx = (400x + -80x2 + 4x3) Solving vx = 400x + -80x2 + 4x3 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Divide each side by 'x'. v = 400 + -80x + 4x2 Simplifying v = 400 + -80x + 4x2
