Simplifying 15x2 + -9x + -31 = -7 Reorder the terms: -31 + -9x + 15x2 = -7 Solving -31 + -9x + 15x2 = -7 Solving for variable 'x'. Reorder the terms: -31 + 7 + -9x + 15x2 = -7 + 7 Combine like terms: -31 + 7 = -24 -24 + -9x + 15x2 = -7 + 7 Combine like terms: -7 + 7 = 0 -24 + -9x + 15x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-8 + -3x + 5x2) = 0 Factor a trinomial. 3((-1 + -1x)(8 + -5x)) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-1 + -1x)' equal to zero and attempt to solve: Simplifying -1 + -1x = 0 Solving -1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + -1x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1x = 0 + 1 -1x = 0 + 1 Combine like terms: 0 + 1 = 1 -1x = 1 Divide each side by '-1'. x = -1 Simplifying x = -1Subproblem 2
Set the factor '(8 + -5x)' equal to zero and attempt to solve: Simplifying 8 + -5x = 0 Solving 8 + -5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + -5x = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -5x = 0 + -8 -5x = 0 + -8 Combine like terms: 0 + -8 = -8 -5x = -8 Divide each side by '-5'. x = 1.6 Simplifying x = 1.6Solution
x = {-1, 1.6}
