Simplifying (k2 + -1k + -20) * 18 = 0 Reorder the terms: (-20 + -1k + k2) * 18 = 0 Reorder the terms for easier multiplication: 18(-20 + -1k + k2) = 0 (-20 * 18 + -1k * 18 + k2 * 18) = 0 (-360 + -18k + 18k2) = 0 Solving -360 + -18k + 18k2 = 0 Solving for variable 'k'. Factor out the Greatest Common Factor (GCF), '18'. 18(-20 + -1k + k2) = 0 Factor a trinomial. 18((-4 + -1k)(5 + -1k)) = 0 Ignore the factor 18.Subproblem 1
Set the factor '(-4 + -1k)' equal to zero and attempt to solve: Simplifying -4 + -1k = 0 Solving -4 + -1k = 0 Move all terms containing k to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + -1k = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1k = 0 + 4 -1k = 0 + 4 Combine like terms: 0 + 4 = 4 -1k = 4 Divide each side by '-1'. k = -4 Simplifying k = -4Subproblem 2
Set the factor '(5 + -1k)' equal to zero and attempt to solve: Simplifying 5 + -1k = 0 Solving 5 + -1k = 0 Move all terms containing k to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1k = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1k = 0 + -5 -1k = 0 + -5 Combine like terms: 0 + -5 = -5 -1k = -5 Divide each side by '-1'. k = 5 Simplifying k = 5Solution
k = {-4, 5}
