Simplifying 2x5 + -5x3 + 4x = 0 Reorder the terms: 4x + -5x3 + 2x5 = 0 Solving 4x + -5x3 + 2x5 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(4 + -5x2 + 2x4) = 0Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(4 + -5x2 + 2x4)' equal to zero and attempt to solve: Simplifying 4 + -5x2 + 2x4 = 0 Solving 4 + -5x2 + 2x4 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2 + -2.5x2 + x4 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -2.5x2 + -2 + x4 = 0 + -2 Reorder the terms: 2 + -2 + -2.5x2 + x4 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -2.5x2 + x4 = 0 + -2 -2.5x2 + x4 = 0 + -2 Combine like terms: 0 + -2 = -2 -2.5x2 + x4 = -2 The x term is -2.5x2. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x2 + 1.5625 + x4 = -2 + 1.5625 Reorder the terms: 1.5625 + -2.5x2 + x4 = -2 + 1.5625 Combine like terms: -2 + 1.5625 = -0.4375 1.5625 + -2.5x2 + x4 = -0.4375 Factor a perfect square on the left side: (x2 + -1.25)(x2 + -1.25) = -0.4375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
