Factor out the Greatest Common Factor (GCF), '3k'. 3k(153 + -84k + 5k2 + 2k3) = 0 Ignore the factor 3.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 '(153 + -84k + 5k2 + 2k3)' equal to zero and attempt to solve: Simplifying 153 + -84k + 5k2 + 2k3 = 0 Solving 153 + -84k + 5k2 + 2k3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
