Simplifying 0 = 4x2 + 2x + -2 Reorder the terms: 0 = -2 + 2x + 4x2 Solving 0 = -2 + 2x + 4x2 Solving for variable 'x'. Combine like terms: 0 + 2 = 2 2 + -2x + -4x2 = -2 + 2x + 4x2 + 2 + -2x + -4x2 Reorder the terms: 2 + -2x + -4x2 = -2 + 2 + 2x + -2x + 4x2 + -4x2 Combine like terms: -2 + 2 = 0 2 + -2x + -4x2 = 0 + 2x + -2x + 4x2 + -4x2 2 + -2x + -4x2 = 2x + -2x + 4x2 + -4x2 Combine like terms: 2x + -2x = 0 2 + -2x + -4x2 = 0 + 4x2 + -4x2 2 + -2x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 2 + -2x + -4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(1 + -1x + -2x2) = 0 Factor a trinomial. 2((1 + -2x)(1 + x)) = 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
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 = {0.5, -1}
