Simplifying 15x4 + -9x2 = 0 Reorder the terms: -9x2 + 15x4 = 0 Solving -9x2 + 15x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3x2'. 3x2(-3 + 5x2) = 0 Ignore the factor 3.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 + 5x2)' equal to zero and attempt to solve: Simplifying -3 + 5x2 = 0 Solving -3 + 5x2 = 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 + 5x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 5x2 = 0 + 3 5x2 = 0 + 3 Combine like terms: 0 + 3 = 3 5x2 = 3 Divide each side by '5'. x2 = 0.6 Simplifying x2 = 0.6 Take the square root of each side: x = {-0.774596669, 0.774596669}Solution
x = {0, -0.774596669, 0.774596669}
