Simplifying 3x2 + -15x = 42 Reorder the terms: -15x + 3x2 = 42 Solving -15x + 3x2 = 42 Solving for variable 'x'. Reorder the terms: -42 + -15x + 3x2 = 42 + -42 Combine like terms: 42 + -42 = 0 -42 + -15x + 3x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-14 + -5x + x2) = 0 Factor a trinomial. 3((-2 + -1x)(7 + -1x)) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-2 + -1x)' equal to zero and attempt to solve: Simplifying -2 + -1x = 0 Solving -2 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -1x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1x = 0 + 2 -1x = 0 + 2 Combine like terms: 0 + 2 = 2 -1x = 2 Divide each side by '-1'. x = -2 Simplifying x = -2Subproblem 2
Set the factor '(7 + -1x)' equal to zero and attempt to solve: Simplifying 7 + -1x = 0 Solving 7 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1x = 0 + -7 -1x = 0 + -7 Combine like terms: 0 + -7 = -7 -1x = -7 Divide each side by '-1'. x = 7 Simplifying x = 7Solution
x = {-2, 7}
