Simplifying 2x2 + -4x + -27 = 3 Reorder the terms: -27 + -4x + 2x2 = 3 Solving -27 + -4x + 2x2 = 3 Solving for variable 'x'. Reorder the terms: -27 + -3 + -4x + 2x2 = 3 + -3 Combine like terms: -27 + -3 = -30 -30 + -4x + 2x2 = 3 + -3 Combine like terms: 3 + -3 = 0 -30 + -4x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-15 + -2x + x2) = 0 Factor a trinomial. 2((-3 + -1x)(5 + -1x)) = 0 Ignore the factor 2.Subproblem 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 '(5 + -1x)' equal to zero and attempt to solve: Simplifying 5 + -1x = 0 Solving 5 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1x = 0 + -5 -1x = 0 + -5 Combine like terms: 0 + -5 = -5 -1x = -5 Divide each side by '-1'. x = 5 Simplifying x = 5Solution
x = {-3, 5}
