Simplifying (3k + -2)(k + 6) = 0 Reorder the terms: (-2 + 3k)(k + 6) = 0 Reorder the terms: (-2 + 3k)(6 + k) = 0 Multiply (-2 + 3k) * (6 + k) (-2(6 + k) + 3k * (6 + k)) = 0 ((6 * -2 + k * -2) + 3k * (6 + k)) = 0 ((-12 + -2k) + 3k * (6 + k)) = 0 (-12 + -2k + (6 * 3k + k * 3k)) = 0 (-12 + -2k + (18k + 3k2)) = 0 Combine like terms: -2k + 18k = 16k (-12 + 16k + 3k2) = 0 Solving -12 + 16k + 3k2 = 0 Solving for variable 'k'. Factor a trinomial. (-6 + -1k)(2 + -3k) = 0Subproblem 1
Set the factor '(-6 + -1k)' equal to zero and attempt to solve: Simplifying -6 + -1k = 0 Solving -6 + -1k = 0 Move all terms containing k to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + -1k = 0 + 6 Combine like terms: -6 + 6 = 0 0 + -1k = 0 + 6 -1k = 0 + 6 Combine like terms: 0 + 6 = 6 -1k = 6 Divide each side by '-1'. k = -6 Simplifying k = -6Subproblem 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 = {-6, 0.6666666667}
