Simplifying x2 + 12x + 15 = 2x + 6 Reorder the terms: 15 + 12x + x2 = 2x + 6 Reorder the terms: 15 + 12x + x2 = 6 + 2x Solving 15 + 12x + x2 = 6 + 2x Solving for variable 'x'. Reorder the terms: 15 + -6 + 12x + -2x + x2 = 6 + 2x + -6 + -2x Combine like terms: 15 + -6 = 9 9 + 12x + -2x + x2 = 6 + 2x + -6 + -2x Combine like terms: 12x + -2x = 10x 9 + 10x + x2 = 6 + 2x + -6 + -2x Reorder the terms: 9 + 10x + x2 = 6 + -6 + 2x + -2x Combine like terms: 6 + -6 = 0 9 + 10x + x2 = 0 + 2x + -2x 9 + 10x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 9 + 10x + x2 = 0 Factor a trinomial. (9 + x)(1 + x) = 0Subproblem 1
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 = -9Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 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 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Solution
x = {-9, -1}
