Simplifying y5 + 18y3 + 81y = 0 Reorder the terms: 81y + 18y3 + y5 = 0 Solving 81y + 18y3 + y5 = 0 Solving for variable 'y'. Factor out the Greatest Common Factor (GCF), 'y'. y(81 + 18y2 + y4) = 0 Factor a trinomial. y((9 + y2)(9 + y2)) = 0Subproblem 1
Set the factor 'y' equal to zero and attempt to solve: Simplifying y = 0 Solving y = 0 Move all terms containing y to the left, all other terms to the right. Simplifying y = 0Subproblem 2
Set the factor '(9 + y2)' equal to zero and attempt to solve: Simplifying 9 + y2 = 0 Solving 9 + y2 = 0 Move all terms containing y to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + y2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + y2 = 0 + -9 y2 = 0 + -9 Combine like terms: 0 + -9 = -9 y2 = -9 Simplifying y2 = -9 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 3
