Simplifying -2x2 + 4x + 6 = 6 Reorder the terms: 6 + 4x + -2x2 = 6 Add '-6' to each side of the equation. 6 + 4x + -6 + -2x2 = 6 + -6 Reorder the terms: 6 + -6 + 4x + -2x2 = 6 + -6 Combine like terms: 6 + -6 = 0 0 + 4x + -2x2 = 6 + -6 4x + -2x2 = 6 + -6 Combine like terms: 6 + -6 = 0 4x + -2x2 = 0 Solving 4x + -2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(2 + -1x) = 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 '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 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 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Divide each side by '-1'. x = 2 Simplifying x = 2Solution
x = {0, 2}
