Simplifying (x + -1)(x + 5) = -8 Reorder the terms: (-1 + x)(x + 5) = -8 Reorder the terms: (-1 + x)(5 + x) = -8 Multiply (-1 + x) * (5 + x) (-1(5 + x) + x(5 + x)) = -8 ((5 * -1 + x * -1) + x(5 + x)) = -8 ((-5 + -1x) + x(5 + x)) = -8 (-5 + -1x + (5 * x + x * x)) = -8 (-5 + -1x + (5x + x2)) = -8 Combine like terms: -1x + 5x = 4x (-5 + 4x + x2) = -8 Solving -5 + 4x + x2 = -8 Solving for variable 'x'. Reorder the terms: -5 + 8 + 4x + x2 = -8 + 8 Combine like terms: -5 + 8 = 3 3 + 4x + x2 = -8 + 8 Combine like terms: -8 + 8 = 0 3 + 4x + x2 = 0 Factor a trinomial. (3 + x)(1 + x) = 0Subproblem 1
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 = -3Subproblem 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 = {-3, -1}
