Simplifying -6k2 + -13k + -6 = 0 Reorder the terms: -6 + -13k + -6k2 = 0 Solving -6 + -13k + -6k2 = 0 Solving for variable 'k'. Factor out the Greatest Common Factor (GCF), '-1'. -1(6 + 13k + 6k2) = 0 Factor a trinomial. -1((3 + 2k)(2 + 3k)) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(3 + 2k)' equal to zero and attempt to solve: Simplifying 3 + 2k = 0 Solving 3 + 2k = 0 Move all terms containing k to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + 2k = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2k = 0 + -3 2k = 0 + -3 Combine like terms: 0 + -3 = -3 2k = -3 Divide each side by '2'. k = -1.5 Simplifying k = -1.5Subproblem 2
Set the factor '(2 + 3k)' equal to zero and attempt to solve: Simplifying 2 + 3k = 0 Solving 2 + 3k = 0 Move all terms containing k to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 3k = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3k = 0 + -2 3k = 0 + -2 Combine like terms: 0 + -2 = -2 3k = -2 Divide each side by '3'. k = -0.6666666667 Simplifying k = -0.6666666667Solution
k = {-1.5, -0.6666666667}
