Simplifying x3 = -4x2 + -4x Reorder the terms: x3 = -4x + -4x2 Solving x3 = -4x + -4x2 Solving for variable 'x'. Reorder the terms: 4x + 4x2 + x3 = -4x + -4x2 + 4x + 4x2 Reorder the terms: 4x + 4x2 + x3 = -4x + 4x + -4x2 + 4x2 Combine like terms: -4x + 4x = 0 4x + 4x2 + x3 = 0 + -4x2 + 4x2 4x + 4x2 + x3 = -4x2 + 4x2 Combine like terms: -4x2 + 4x2 = 0 4x + 4x2 + x3 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(4 + 4x + x2) = 0 Factor a trinomial. 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
