Simplifying -1(x2 + -13x) = -1(3x2 + -5x) Reorder the terms: -1(-13x + x2) = -1(3x2 + -5x) (-13x * -1 + x2 * -1) = -1(3x2 + -5x) (13x + -1x2) = -1(3x2 + -5x) Reorder the terms: 13x + -1x2 = -1(-5x + 3x2) 13x + -1x2 = (-5x * -1 + 3x2 * -1) 13x + -1x2 = (5x + -3x2) Solving 13x + -1x2 = 5x + -3x2 Solving for variable 'x'. Reorder the terms: 13x + -5x + -1x2 + 3x2 = 5x + -3x2 + -5x + 3x2 Combine like terms: 13x + -5x = 8x 8x + -1x2 + 3x2 = 5x + -3x2 + -5x + 3x2 Combine like terms: -1x2 + 3x2 = 2x2 8x + 2x2 = 5x + -3x2 + -5x + 3x2 Reorder the terms: 8x + 2x2 = 5x + -5x + -3x2 + 3x2 Combine like terms: 5x + -5x = 0 8x + 2x2 = 0 + -3x2 + 3x2 8x + 2x2 = -3x2 + 3x2 Combine like terms: -3x2 + 3x2 = 0 8x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2x'. 2x(4 + x) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
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 = -4Solution
x = {0, -4}
