Combine like terms: -27 + 27 = 0
24 + -22x + -2x2 = 0 + 24x + -24x + 3x2 + -3x2
24 + -22x + -2x2 = 24x + -24x + 3x2 + -3x2

Combine like terms: 24x + -24x = 0
24 + -22x + -2x2 = 0 + 3x2 + -3x2
24 + -22x + -2x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
24 + -22x + -2x2 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(12 + -11x + -1x2) = 0

Factor a trinomial.
2((1 + -1x)(12 + x)) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 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 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1

Subproblem 2

Set the factor '(12 + x)' equal to zero and attempt to solve: Simplifying 12 + x = 0 Solving 12 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = 0 + -12 Combine like terms: 12 + -12 = 0 0 + x = 0 + -12 x = 0 + -12 Combine like terms: 0 + -12 = -12 x = -12 Simplifying x = -12

Solution

x = {1, -12}
