Simplifying 0 = 30x + -1x2 + -81 Reorder the terms: 0 = -81 + 30x + -1x2 Solving 0 = -81 + 30x + -1x2 Solving for variable 'x'. Combine like terms: 0 + 81 = 81 81 + -30x + x2 = -81 + 30x + -1x2 + 81 + -30x + x2 Reorder the terms: 81 + -30x + x2 = -81 + 81 + 30x + -30x + -1x2 + x2 Combine like terms: -81 + 81 = 0 81 + -30x + x2 = 0 + 30x + -30x + -1x2 + x2 81 + -30x + x2 = 30x + -30x + -1x2 + x2 Combine like terms: 30x + -30x = 0 81 + -30x + x2 = 0 + -1x2 + x2 81 + -30x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 81 + -30x + x2 = 0 Factor a trinomial. (3 + -1x)(27 + -1x) = 0Subproblem 1
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 = 3Subproblem 2
Set the factor '(27 + -1x)' equal to zero and attempt to solve: Simplifying 27 + -1x = 0 Solving 27 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-27' to each side of the equation. 27 + -27 + -1x = 0 + -27 Combine like terms: 27 + -27 = 0 0 + -1x = 0 + -27 -1x = 0 + -27 Combine like terms: 0 + -27 = -27 -1x = -27 Divide each side by '-1'. x = 27 Simplifying x = 27Solution
x = {3, 27}
