Simplifying 3x4 + 6 = -9x2 Reorder the terms: 6 + 3x4 = -9x2 Solving 6 + 3x4 = -9x2 Solving for variable 'x'. Reorder the terms: 6 + 9x2 + 3x4 = -9x2 + 9x2 Combine like terms: -9x2 + 9x2 = 0 6 + 9x2 + 3x4 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(2 + 3x2 + x4) = 0 Factor a trinomial. 3((2 + x2)(1 + x2)) = 0 Ignore the factor 3.Subproblem 1
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.Subproblem 2
Set the factor '(1 + x2)' equal to zero and attempt to solve: Simplifying 1 + x2 = 0 Solving 1 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x2 = 0 + -1 x2 = 0 + -1 Combine like terms: 0 + -1 = -1 x2 = -1 Simplifying x2 = -1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
