Simplifying 40x2 + 20x2 + 30x4 = 0 Combine like terms: 40x2 + 20x2 = 60x2 60x2 + 30x4 = 0 Solving 60x2 + 30x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '30x2'. 30x2(2 + x2) = 0 Ignore the factor 30.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 '(2 + x2)' equal to zero and attempt to solve: Simplifying 2 + x2 = 0 Solving 2 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x2 = 0 + -2 x2 = 0 + -2 Combine like terms: 0 + -2 = -2 x2 = -2 Simplifying x2 = -2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
