Simplifying 0 = 2x4 + 18x2 Reorder the terms: 0 = 18x2 + 2x4 Solving 0 = 18x2 + 2x4 Solving for variable 'x'. Remove the zero: -18x2 + -2x4 = 18x2 + 2x4 + -18x2 + -2x4 Reorder the terms: -18x2 + -2x4 = 18x2 + -18x2 + 2x4 + -2x4 Combine like terms: 18x2 + -18x2 = 0 -18x2 + -2x4 = 0 + 2x4 + -2x4 -18x2 + -2x4 = 2x4 + -2x4 Combine like terms: 2x4 + -2x4 = 0 -18x2 + -2x4 = 0 Factor out the Greatest Common Factor (GCF), '-2x2'. -2x2(9 + x2) = 0 Ignore the factor -2.Subproblem 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 '(9 + x2)' equal to zero and attempt to solve: Simplifying 9 + x2 = 0 Solving 9 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + x2 = 0 + -9 x2 = 0 + -9 Combine like terms: 0 + -9 = -9 x2 = -9 Simplifying x2 = -9 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
