Simplifying (20 + 2x) * x(10 + 2x) = 320 Reorder the terms for easier multiplication: x(20 + 2x)(10 + 2x) = 320 Multiply (20 + 2x) * (10 + 2x) x(20(10 + 2x) + 2x * (10 + 2x)) = 320 x((10 * 20 + 2x * 20) + 2x * (10 + 2x)) = 320 x((200 + 40x) + 2x * (10 + 2x)) = 320 x(200 + 40x + (10 * 2x + 2x * 2x)) = 320 x(200 + 40x + (20x + 4x2)) = 320 Combine like terms: 40x + 20x = 60x x(200 + 60x + 4x2) = 320 (200 * x + 60x * x + 4x2 * x) = 320 (200x + 60x2 + 4x3) = 320 Solving 200x + 60x2 + 4x3 = 320 Solving for variable 'x'. Reorder the terms: -320 + 200x + 60x2 + 4x3 = 320 + -320 Combine like terms: 320 + -320 = 0 -320 + 200x + 60x2 + 4x3 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-80 + 50x + 15x2 + x3) = 0 Ignore the factor 4.Subproblem 1
