Simplifying x4 = -81x2 Solving x4 = -81x2 Solving for variable 'x'. Reorder the terms: 81x2 + x4 = -81x2 + 81x2 Combine like terms: -81x2 + 81x2 = 0 81x2 + x4 = 0 Factor out the Greatest Common Factor (GCF), 'x2'. x2(81 + x2) = 0Subproblem 1
Set the factor 'x2' equal to zero and attempt to solve: Simplifying x2 = 0 Solving x2 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x2 = 0 Take the square root of each side: x = {0}Subproblem 2
Set the factor '(81 + x2)' equal to zero and attempt to solve: Simplifying 81 + x2 = 0 Solving 81 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-81' to each side of the equation. 81 + -81 + x2 = 0 + -81 Combine like terms: 81 + -81 = 0 0 + x2 = 0 + -81 x2 = 0 + -81 Combine like terms: 0 + -81 = -81 x2 = -81 Simplifying x2 = -81 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
