Simplifying 0 = 3x2 + -18x + -81 Reorder the terms: 0 = -81 + -18x + 3x2 Solving 0 = -81 + -18x + 3x2 Solving for variable 'x'. Combine like terms: 0 + 81 = 81 81 + 18x + -3x2 = -81 + -18x + 3x2 + 81 + 18x + -3x2 Reorder the terms: 81 + 18x + -3x2 = -81 + 81 + -18x + 18x + 3x2 + -3x2 Combine like terms: -81 + 81 = 0 81 + 18x + -3x2 = 0 + -18x + 18x + 3x2 + -3x2 81 + 18x + -3x2 = -18x + 18x + 3x2 + -3x2 Combine like terms: -18x + 18x = 0 81 + 18x + -3x2 = 0 + 3x2 + -3x2 81 + 18x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 81 + 18x + -3x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(27 + 6x + -1x2) = 0 Factor a trinomial. 3((9 + -1x)(3 + x)) = 0 Ignore the factor 3.Subproblem 1
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 = 9Subproblem 2
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 = -3Solution
x = {9, -3}
