Simplifying -9k + -4k2 = 0 Solving -9k + -4k2 = 0 Solving for variable 'k'. Factor out the Greatest Common Factor (GCF), '-1k'. -1k(9 + 4k) = 0 Ignore the factor -1.Subproblem 1
Set the factor 'k' equal to zero and attempt to solve: Simplifying k = 0 Solving k = 0 Move all terms containing k to the left, all other terms to the right. Simplifying k = 0Subproblem 2
Set the factor '(9 + 4k)' equal to zero and attempt to solve: Simplifying 9 + 4k = 0 Solving 9 + 4k = 0 Move all terms containing k to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 4k = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 4k = 0 + -9 4k = 0 + -9 Combine like terms: 0 + -9 = -9 4k = -9 Divide each side by '4'. k = -2.25 Simplifying k = -2.25Solution
k = {0, -2.25}
