Simplifying 144 = x2 + 18x + 81 Reorder the terms: 144 = 81 + 18x + x2 Solving 144 = 81 + 18x + x2 Solving for variable 'x'. Combine like terms: 144 + -81 = 63 63 + -18x + -1x2 = 81 + 18x + x2 + -81 + -18x + -1x2 Reorder the terms: 63 + -18x + -1x2 = 81 + -81 + 18x + -18x + x2 + -1x2 Combine like terms: 81 + -81 = 0 63 + -18x + -1x2 = 0 + 18x + -18x + x2 + -1x2 63 + -18x + -1x2 = 18x + -18x + x2 + -1x2 Combine like terms: 18x + -18x = 0 63 + -18x + -1x2 = 0 + x2 + -1x2 63 + -18x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 63 + -18x + -1x2 = 0 Factor a trinomial. (3 + -1x)(21 + x) = 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 '(21 + x)' equal to zero and attempt to solve: Simplifying 21 + x = 0 Solving 21 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-21' to each side of the equation. 21 + -21 + x = 0 + -21 Combine like terms: 21 + -21 = 0 0 + x = 0 + -21 x = 0 + -21 Combine like terms: 0 + -21 = -21 x = -21 Simplifying x = -21Solution
x = {3, -21}
