Simplifying (x + 2)(x + 12) = 0 Reorder the terms: (2 + x)(x + 12) = 0 Reorder the terms: (2 + x)(12 + x) = 0 Multiply (2 + x) * (12 + x) (2(12 + x) + x(12 + x)) = 0 ((12 * 2 + x * 2) + x(12 + x)) = 0 ((24 + 2x) + x(12 + x)) = 0 (24 + 2x + (12 * x + x * x)) = 0 (24 + 2x + (12x + x2)) = 0 Combine like terms: 2x + 12x = 14x (24 + 14x + x2) = 0 Solving 24 + 14x + x2 = 0 Solving for variable 'x'. Factor a trinomial. (12 + x)(2 + x) = 0Subproblem 1
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 = -12Subproblem 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 = {-12, -2}
