Simplifying -2x2 + 5x + 30 = -3x + 6 Reorder the terms: 30 + 5x + -2x2 = -3x + 6 Reorder the terms: 30 + 5x + -2x2 = 6 + -3x Solving 30 + 5x + -2x2 = 6 + -3x Solving for variable 'x'. Reorder the terms: 30 + -6 + 5x + 3x + -2x2 = 6 + -3x + -6 + 3x Combine like terms: 30 + -6 = 24 24 + 5x + 3x + -2x2 = 6 + -3x + -6 + 3x Combine like terms: 5x + 3x = 8x 24 + 8x + -2x2 = 6 + -3x + -6 + 3x Reorder the terms: 24 + 8x + -2x2 = 6 + -6 + -3x + 3x Combine like terms: 6 + -6 = 0 24 + 8x + -2x2 = 0 + -3x + 3x 24 + 8x + -2x2 = -3x + 3x Combine like terms: -3x + 3x = 0 24 + 8x + -2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(12 + 4x + -1x2) = 0 Factor a trinomial. 2((6 + -1x)(2 + x)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(6 + -1x)' equal to zero and attempt to solve: Simplifying 6 + -1x = 0 Solving 6 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1x = 0 + -6 -1x = 0 + -6 Combine like terms: 0 + -6 = -6 -1x = -6 Divide each side by '-1'. x = 6 Simplifying x = 6Subproblem 2
Set the factor '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 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 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Simplifying x = -2Solution
x = {6, -2}
