Simplifying 12x4 = 18x2 Solving 12x4 = 18x2 Solving for variable 'x'. Reorder the terms: -18x2 + 12x4 = 18x2 + -18x2 Combine like terms: 18x2 + -18x2 = 0 -18x2 + 12x4 = 0 Factor out the Greatest Common Factor (GCF), '6x2'. 6x2(-3 + 2x2) = 0 Ignore the factor 6.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 '(-3 + 2x2)' equal to zero and attempt to solve: Simplifying -3 + 2x2 = 0 Solving -3 + 2x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 2x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2x2 = 0 + 3 2x2 = 0 + 3 Combine like terms: 0 + 3 = 3 2x2 = 3 Divide each side by '2'. x2 = 1.5 Simplifying x2 = 1.5 Take the square root of each side: x = {-1.224744871, 1.224744871}Solution
x = {0, -1.224744871, 1.224744871}
