Simplifying 2x2 + 2x + -12 = -12 Reorder the terms: -12 + 2x + 2x2 = -12 Add '12' to each side of the equation. -12 + 2x + 12 + 2x2 = -12 + 12 Reorder the terms: -12 + 12 + 2x + 2x2 = -12 + 12 Combine like terms: -12 + 12 = 0 0 + 2x + 2x2 = -12 + 12 2x + 2x2 = -12 + 12 Combine like terms: -12 + 12 = 0 2x + 2x2 = 0 Solving 2x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(1 + 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 '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Solution
x = {0, -1}
