Simplifying (x + 2)(x + 5) = -2 Reorder the terms: (2 + x)(x + 5) = -2 Reorder the terms: (2 + x)(5 + x) = -2 Multiply (2 + x) * (5 + x) (2(5 + x) + x(5 + x)) = -2 ((5 * 2 + x * 2) + x(5 + x)) = -2 ((10 + 2x) + x(5 + x)) = -2 (10 + 2x + (5 * x + x * x)) = -2 (10 + 2x + (5x + x2)) = -2 Combine like terms: 2x + 5x = 7x (10 + 7x + x2) = -2 Solving 10 + 7x + x2 = -2 Solving for variable 'x'. Reorder the terms: 10 + 2 + 7x + x2 = -2 + 2 Combine like terms: 10 + 2 = 12 12 + 7x + x2 = -2 + 2 Combine like terms: -2 + 2 = 0 12 + 7x + x2 = 0 Factor a trinomial. (4 + x)(3 + x) = 0Subproblem 1
Set the factor '(4 + x)' equal to zero and attempt to solve: Simplifying 4 + x = 0 Solving 4 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + x = 0 + -4 x = 0 + -4 Combine like terms: 0 + -4 = -4 x = -4 Simplifying x = -4Subproblem 2
Set the factor '(3 + x)' equal to zero and attempt to solve: Simplifying 3 + x = 0 Solving 3 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x = 0 + -3 x = 0 + -3 Combine like terms: 0 + -3 = -3 x = -3 Simplifying x = -3Solution
x = {-4, -3}
