Simplifying (2x + -13)(12x + 7) = -91 Reorder the terms: (-13 + 2x)(12x + 7) = -91 Reorder the terms: (-13 + 2x)(7 + 12x) = -91 Multiply (-13 + 2x) * (7 + 12x) (-13(7 + 12x) + 2x * (7 + 12x)) = -91 ((7 * -13 + 12x * -13) + 2x * (7 + 12x)) = -91 ((-91 + -156x) + 2x * (7 + 12x)) = -91 (-91 + -156x + (7 * 2x + 12x * 2x)) = -91 (-91 + -156x + (14x + 24x2)) = -91 Combine like terms: -156x + 14x = -142x (-91 + -142x + 24x2) = -91 Add '91' to each side of the equation. -91 + -142x + 91 + 24x2 = -91 + 91 Reorder the terms: -91 + 91 + -142x + 24x2 = -91 + 91 Combine like terms: -91 + 91 = 0 0 + -142x + 24x2 = -91 + 91 -142x + 24x2 = -91 + 91 Combine like terms: -91 + 91 = 0 -142x + 24x2 = 0 Solving -142x + 24x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(-71 + 12x) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(-71 + 12x)' equal to zero and attempt to solve: Simplifying -71 + 12x = 0 Solving -71 + 12x = 0 Move all terms containing x to the left, all other terms to the right. Add '71' to each side of the equation. -71 + 71 + 12x = 0 + 71 Combine like terms: -71 + 71 = 0 0 + 12x = 0 + 71 12x = 0 + 71 Combine like terms: 0 + 71 = 71 12x = 71 Divide each side by '12'. x = 5.916666667 Simplifying x = 5.916666667Solution
x = {0, 5.916666667}
