Simplifying x3 + x2 + -6x = x2 + -2x Reorder the terms: -6x + x2 + x3 = x2 + -2x Reorder the terms: -6x + x2 + x3 = -2x + x2 Add '-1x2' to each side of the equation. -6x + x2 + -1x2 + x3 = -2x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -6x + 0 + x3 = -2x + x2 + -1x2 -6x + x3 = -2x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -6x + x3 = -2x + 0 -6x + x3 = -2x Solving -6x + x3 = -2x Solving for variable 'x'. Reorder the terms: -6x + 2x + x3 = -2x + 2x Combine like terms: -6x + 2x = -4x -4x + x3 = -2x + 2x Combine like terms: -2x + 2x = 0 -4x + x3 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-4 + x2) = 0 Factor a difference between two squares. x((2 + x)(-2 + x)) = 0Subproblem 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 '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Simplifying x = -2Subproblem 3
Set the factor '(-2 + x)' equal to zero and attempt to solve: Simplifying -2 + x = 0 Solving -2 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + x = 0 + 2 x = 0 + 2 Combine like terms: 0 + 2 = 2 x = 2 Simplifying x = 2Solution
x = {0, -2, 2}
