Simplifying 0 = -5x2 + -21x + -18 Reorder the terms: 0 = -18 + -21x + -5x2 Solving 0 = -18 + -21x + -5x2 Solving for variable 'x'. Combine like terms: 0 + 18 = 18 18 + 21x + 5x2 = -18 + -21x + -5x2 + 18 + 21x + 5x2 Reorder the terms: 18 + 21x + 5x2 = -18 + 18 + -21x + 21x + -5x2 + 5x2 Combine like terms: -18 + 18 = 0 18 + 21x + 5x2 = 0 + -21x + 21x + -5x2 + 5x2 18 + 21x + 5x2 = -21x + 21x + -5x2 + 5x2 Combine like terms: -21x + 21x = 0 18 + 21x + 5x2 = 0 + -5x2 + 5x2 18 + 21x + 5x2 = -5x2 + 5x2 Combine like terms: -5x2 + 5x2 = 0 18 + 21x + 5x2 = 0 Factor a trinomial. (3 + x)(6 + 5x) = 0Subproblem 1
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 = -3Subproblem 2
Set the factor '(6 + 5x)' equal to zero and attempt to solve: Simplifying 6 + 5x = 0 Solving 6 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + 5x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + 5x = 0 + -6 5x = 0 + -6 Combine like terms: 0 + -6 = -6 5x = -6 Divide each side by '5'. x = -1.2 Simplifying x = -1.2Solution
x = {-3, -1.2}
