Simplifying -3x2 + 6x + 2 = x2 + 2 Reorder the terms: 2 + 6x + -3x2 = x2 + 2 Reorder the terms: 2 + 6x + -3x2 = 2 + x2 Add '-2' to each side of the equation. 2 + 6x + -2 + -3x2 = 2 + -2 + x2 Reorder the terms: 2 + -2 + 6x + -3x2 = 2 + -2 + x2 Combine like terms: 2 + -2 = 0 0 + 6x + -3x2 = 2 + -2 + x2 6x + -3x2 = 2 + -2 + x2 Combine like terms: 2 + -2 = 0 6x + -3x2 = 0 + x2 6x + -3x2 = x2 Solving 6x + -3x2 = x2 Solving for variable 'x'. Combine like terms: -3x2 + -1x2 = -4x2 6x + -4x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 6x + -4x2 = 0 Factor out the Greatest Common Factor (GCF), '2x'. 2x(3 + -2x) = 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 '(3 + -2x)' equal to zero and attempt to solve: Simplifying 3 + -2x = 0 Solving 3 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2x = 0 + -3 -2x = 0 + -3 Combine like terms: 0 + -3 = -3 -2x = -3 Divide each side by '-2'. x = 1.5 Simplifying x = 1.5Solution
x = {0, 1.5}
