Simplifying (x + -5)(2x + 5) = -22 Reorder the terms: (-5 + x)(2x + 5) = -22 Reorder the terms: (-5 + x)(5 + 2x) = -22 Multiply (-5 + x) * (5 + 2x) (-5(5 + 2x) + x(5 + 2x)) = -22 ((5 * -5 + 2x * -5) + x(5 + 2x)) = -22 ((-25 + -10x) + x(5 + 2x)) = -22 (-25 + -10x + (5 * x + 2x * x)) = -22 (-25 + -10x + (5x + 2x2)) = -22 Combine like terms: -10x + 5x = -5x (-25 + -5x + 2x2) = -22 Solving -25 + -5x + 2x2 = -22 Solving for variable 'x'. Reorder the terms: -25 + 22 + -5x + 2x2 = -22 + 22 Combine like terms: -25 + 22 = -3 -3 + -5x + 2x2 = -22 + 22 Combine like terms: -22 + 22 = 0 -3 + -5x + 2x2 = 0 Factor a trinomial. (-1 + -2x)(3 + -1x) = 0Subproblem 1
Set the factor '(-1 + -2x)' equal to zero and attempt to solve: Simplifying -1 + -2x = 0 Solving -1 + -2x = 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 + -2x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -2x = 0 + 1 -2x = 0 + 1 Combine like terms: 0 + 1 = 1 -2x = 1 Divide each side by '-2'. x = -0.5 Simplifying x = -0.5Subproblem 2
Set the factor '(3 + -1x)' equal to zero and attempt to solve: Simplifying 3 + -1x = 0 Solving 3 + -1x = 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 + -1x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1x = 0 + -3 -1x = 0 + -3 Combine like terms: 0 + -3 = -3 -1x = -3 Divide each side by '-1'. x = 3 Simplifying x = 3Solution
x = {-0.5, 3}
