Simplifying (x + -9)(x + 7) = 0 Reorder the terms: (-9 + x)(x + 7) = 0 Reorder the terms: (-9 + x)(7 + x) = 0 Multiply (-9 + x) * (7 + x) (-9(7 + x) + x(7 + x)) = 0 ((7 * -9 + x * -9) + x(7 + x)) = 0 ((-63 + -9x) + x(7 + x)) = 0 (-63 + -9x + (7 * x + x * x)) = 0 (-63 + -9x + (7x + x2)) = 0 Combine like terms: -9x + 7x = -2x (-63 + -2x + x2) = 0 Solving -63 + -2x + x2 = 0 Solving for variable 'x'. Factor a trinomial. (-7 + -1x)(9 + -1x) = 0Subproblem 1
Set the factor '(-7 + -1x)' equal to zero and attempt to solve: Simplifying -7 + -1x = 0 Solving -7 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1x = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1x = 0 + 7 -1x = 0 + 7 Combine like terms: 0 + 7 = 7 -1x = 7 Divide each side by '-1'. x = -7 Simplifying x = -7Subproblem 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 = {-7, 9}
