Simplifying x(x + 9) = -2(x + 9) Reorder the terms: x(9 + x) = -2(x + 9) (9 * x + x * x) = -2(x + 9) (9x + x2) = -2(x + 9) Reorder the terms: 9x + x2 = -2(9 + x) 9x + x2 = (9 * -2 + x * -2) 9x + x2 = (-18 + -2x) Solving 9x + x2 = -18 + -2x Solving for variable 'x'. Reorder the terms: 18 + 9x + 2x + x2 = -18 + -2x + 18 + 2x Combine like terms: 9x + 2x = 11x 18 + 11x + x2 = -18 + -2x + 18 + 2x Reorder the terms: 18 + 11x + x2 = -18 + 18 + -2x + 2x Combine like terms: -18 + 18 = 0 18 + 11x + x2 = 0 + -2x + 2x 18 + 11x + x2 = -2x + 2x Combine like terms: -2x + 2x = 0 18 + 11x + x2 = 0 Factor a trinomial. (9 + x)(2 + 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 '(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 = {-9, -2}
