Simplifying (x + -9)(x + -9) = 81 Reorder the terms: (-9 + x)(x + -9) = 81 Reorder the terms: (-9 + x)(-9 + x) = 81 Multiply (-9 + x) * (-9 + x) (-9(-9 + x) + x(-9 + x)) = 81 ((-9 * -9 + x * -9) + x(-9 + x)) = 81 ((81 + -9x) + x(-9 + x)) = 81 (81 + -9x + (-9 * x + x * x)) = 81 (81 + -9x + (-9x + x2)) = 81 Combine like terms: -9x + -9x = -18x (81 + -18x + x2) = 81 Add '-81' to each side of the equation. 81 + -18x + -81 + x2 = 81 + -81 Reorder the terms: 81 + -81 + -18x + x2 = 81 + -81 Combine like terms: 81 + -81 = 0 0 + -18x + x2 = 81 + -81 -18x + x2 = 81 + -81 Combine like terms: 81 + -81 = 0 -18x + x2 = 0 Solving -18x + x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(-18 + x) = 0Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(-18 + x)' equal to zero and attempt to solve: Simplifying -18 + x = 0 Solving -18 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '18' to each side of the equation. -18 + 18 + x = 0 + 18 Combine like terms: -18 + 18 = 0 0 + x = 0 + 18 x = 0 + 18 Combine like terms: 0 + 18 = 18 x = 18 Simplifying x = 18Solution
x = {0, 18}
