Simplifying 81a + 3a4 = 0 Solving 81a + 3a4 = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '3a'. 3a(27 + a3) = 0 Ignore the factor 3.Subproblem 1
Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0Subproblem 2
Set the factor '(27 + a3)' equal to zero and attempt to solve: Simplifying 27 + a3 = 0 Solving 27 + a3 = 0 Move all terms containing a to the left, all other terms to the right. Add '-27' to each side of the equation. 27 + -27 + a3 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + a3 = 0 + -27 a3 = 0 + -27 Combine like terms: 0 + -27 = -27 a3 = -27 Simplifying a3 = -27 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
