Simplifying x(x + -9) + 4(x + -9) = 0 Reorder the terms: x(-9 + x) + 4(x + -9) = 0 (-9 * x + x * x) + 4(x + -9) = 0 (-9x + x2) + 4(x + -9) = 0 Reorder the terms: -9x + x2 + 4(-9 + x) = 0 -9x + x2 + (-9 * 4 + x * 4) = 0 -9x + x2 + (-36 + 4x) = 0 Reorder the terms: -36 + -9x + 4x + x2 = 0 Combine like terms: -9x + 4x = -5x -36 + -5x + x2 = 0 Solving -36 + -5x + x2 = 0 Solving for variable 'x'. Factor a trinomial. (-4 + -1x)(9 + -1x) = 0Subproblem 1
Set the factor '(-4 + -1x)' equal to zero and attempt to solve: Simplifying -4 + -1x = 0 Solving -4 + -1x = 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 + -1x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1x = 0 + 4 -1x = 0 + 4 Combine like terms: 0 + 4 = 4 -1x = 4 Divide each side by '-1'. x = -4 Simplifying x = -4Subproblem 2
Set the factor '(9 + -1x)' equal to zero and attempt to solve: Simplifying 9 + -1x = 0 Solving 9 + -1x = 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 + -1x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = 0 + -9 -1x = 0 + -9 Combine like terms: 0 + -9 = -9 -1x = -9 Divide each side by '-1'. x = 9 Simplifying x = 9Solution
x = {-4, 9}
