Simplifying 9k = 84 + -3k(k) Multiply k * k 9k = 84 + -3k2 Solving 9k = 84 + -3k2 Solving for variable 'k'. Reorder the terms: -84 + 9k + 3k2 = 84 + -3k2 + -84 + 3k2 Reorder the terms: -84 + 9k + 3k2 = 84 + -84 + -3k2 + 3k2 Combine like terms: 84 + -84 = 0 -84 + 9k + 3k2 = 0 + -3k2 + 3k2 -84 + 9k + 3k2 = -3k2 + 3k2 Combine like terms: -3k2 + 3k2 = 0 -84 + 9k + 3k2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-28 + 3k + k2) = 0 Factor a trinomial. 3((-7 + -1k)(4 + -1k)) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-7 + -1k)' equal to zero and attempt to solve: Simplifying -7 + -1k = 0 Solving -7 + -1k = 0 Move all terms containing k to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1k = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1k = 0 + 7 -1k = 0 + 7 Combine like terms: 0 + 7 = 7 -1k = 7 Divide each side by '-1'. k = -7 Simplifying k = -7Subproblem 2
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 = 4Solution
k = {-7, 4}
