Simplifying x5 + -5x3 + -2x = 0 Reorder the terms: -2x + -5x3 + x5 = 0 Solving -2x + -5x3 + x5 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(-2 + -5x2 + x4) = 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 '(-2 + -5x2 + x4)' equal to zero and attempt to solve: Simplifying -2 + -5x2 + x4 = 0 Solving -2 + -5x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + -5x2 + 2 + x4 = 0 + 2 Reorder the terms: -2 + 2 + -5x2 + x4 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -5x2 + x4 = 0 + 2 -5x2 + x4 = 0 + 2 Combine like terms: 0 + 2 = 2 -5x2 + x4 = 2 The x term is -5x2. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x2 + 6.25 + x4 = 2 + 6.25 Reorder the terms: 6.25 + -5x2 + x4 = 2 + 6.25 Combine like terms: 2 + 6.25 = 8.25 6.25 + -5x2 + x4 = 8.25 Factor a perfect square on the left side: (x2 + -2.5)(x2 + -2.5) = 8.25 Calculate the square root of the right side: 2.872281323 Break this problem into two subproblems by setting (x2 + -2.5) equal to 2.872281323 and -2.872281323.Subproblem 1
x2 + -2.5 = 2.872281323 Simplifying x2 + -2.5 = 2.872281323 Reorder the terms: -2.5 + x2 = 2.872281323 Solving -2.5 + x2 = 2.872281323 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x2 = 2.872281323 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x2 = 2.872281323 + 2.5 x2 = 2.872281323 + 2.5 Combine like terms: 2.872281323 + 2.5 = 5.372281323 x2 = 5.372281323 Simplifying x2 = 5.372281323 Take the square root of each side: x = {-2.317818225, 2.317818225}Subproblem 2
