Simplifying 8x2 + 8x = -2 Reorder the terms: 8x + 8x2 = -2 Solving 8x + 8x2 = -2 Solving for variable 'x'. Reorder the terms: 2 + 8x + 8x2 = -2 + 2 Combine like terms: -2 + 2 = 0 2 + 8x + 8x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(1 + 4x + 4x2) = 0 Factor a trinomial. 2((1 + 2x)(1 + 2x)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(1 + 2x)' equal to zero and attempt to solve: Simplifying 1 + 2x = 0 Solving 1 + 2x = 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 + 2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 2x = 0 + -1 2x = 0 + -1 Combine like terms: 0 + -1 = -1 2x = -1 Divide each side by '2'. x = -0.5 Simplifying x = -0.5Subproblem 2
