Simplifying (2 + x)(200 + -20x) = 720 Multiply (2 + x) * (200 + -20x) (2(200 + -20x) + x(200 + -20x)) = 720 ((200 * 2 + -20x * 2) + x(200 + -20x)) = 720 ((400 + -40x) + x(200 + -20x)) = 720 (400 + -40x + (200 * x + -20x * x)) = 720 (400 + -40x + (200x + -20x2)) = 720 Combine like terms: -40x + 200x = 160x (400 + 160x + -20x2) = 720 Solving 400 + 160x + -20x2 = 720 Solving for variable 'x'. Reorder the terms: 400 + -720 + 160x + -20x2 = 720 + -720 Combine like terms: 400 + -720 = -320 -320 + 160x + -20x2 = 720 + -720 Combine like terms: 720 + -720 = 0 -320 + 160x + -20x2 = 0 Factor out the Greatest Common Factor (GCF), '20'. 20(-16 + 8x + -1x2) = 0 Factor a trinomial. 20((-4 + x)(4 + -1x)) = 0 Ignore the factor 20.Subproblem 1
Set the factor '(-4 + x)' equal to zero and attempt to solve: Simplifying -4 + x = 0 Solving -4 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + x = 0 + 4 x = 0 + 4 Combine like terms: 0 + 4 = 4 x = 4 Simplifying x = 4Subproblem 2
Set the factor '(4 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Divide each side by '-1'. x = 4 Simplifying x = 4Solution
x = {4, 4}
