Simplifying x(x + 3) + 66 = (x + -1)(2x + 6) Reorder the terms: x(3 + x) + 66 = (x + -1)(2x + 6) (3 * x + x * x) + 66 = (x + -1)(2x + 6) (3x + x2) + 66 = (x + -1)(2x + 6) Reorder the terms: 66 + 3x + x2 = (x + -1)(2x + 6) Reorder the terms: 66 + 3x + x2 = (-1 + x)(2x + 6) Reorder the terms: 66 + 3x + x2 = (-1 + x)(6 + 2x) Multiply (-1 + x) * (6 + 2x) 66 + 3x + x2 = (-1(6 + 2x) + x(6 + 2x)) 66 + 3x + x2 = ((6 * -1 + 2x * -1) + x(6 + 2x)) 66 + 3x + x2 = ((-6 + -2x) + x(6 + 2x)) 66 + 3x + x2 = (-6 + -2x + (6 * x + 2x * x)) 66 + 3x + x2 = (-6 + -2x + (6x + 2x2)) Combine like terms: -2x + 6x = 4x 66 + 3x + x2 = (-6 + 4x + 2x2) Solving 66 + 3x + x2 = -6 + 4x + 2x2 Solving for variable 'x'. Reorder the terms: 66 + 6 + 3x + -4x + x2 + -2x2 = -6 + 4x + 2x2 + 6 + -4x + -2x2 Combine like terms: 66 + 6 = 72 72 + 3x + -4x + x2 + -2x2 = -6 + 4x + 2x2 + 6 + -4x + -2x2 Combine like terms: 3x + -4x = -1x 72 + -1x + x2 + -2x2 = -6 + 4x + 2x2 + 6 + -4x + -2x2 Combine like terms: x2 + -2x2 = -1x2 72 + -1x + -1x2 = -6 + 4x + 2x2 + 6 + -4x + -2x2 Reorder the terms: 72 + -1x + -1x2 = -6 + 6 + 4x + -4x + 2x2 + -2x2 Combine like terms: -6 + 6 = 0 72 + -1x + -1x2 = 0 + 4x + -4x + 2x2 + -2x2 72 + -1x + -1x2 = 4x + -4x + 2x2 + -2x2 Combine like terms: 4x + -4x = 0 72 + -1x + -1x2 = 0 + 2x2 + -2x2 72 + -1x + -1x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 72 + -1x + -1x2 = 0 Factor a trinomial. (8 + -1x)(9 + x) = 0Subproblem 1
Set the factor '(8 + -1x)' equal to zero and attempt to solve: Simplifying 8 + -1x = 0 Solving 8 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + -1x = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -1x = 0 + -8 -1x = 0 + -8 Combine like terms: 0 + -8 = -8 -1x = -8 Divide each side by '-1'. x = 8 Simplifying x = 8Subproblem 2
Set the factor '(9 + x)' equal to zero and attempt to solve: Simplifying 9 + x = 0 Solving 9 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + x = 0 + -9 x = 0 + -9 Combine like terms: 0 + -9 = -9 x = -9 Simplifying x = -9Solution
x = {8, -9}
