Simplifying x5 + 15x3 + 20x = 0 Reorder the terms: 20x + 15x3 + x5 = 0 Solving 20x + 15x3 + x5 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(20 + 15x2 + 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 '(20 + 15x2 + x4)' equal to zero and attempt to solve: Simplifying 20 + 15x2 + x4 = 0 Solving 20 + 15x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + 15x2 + -20 + x4 = 0 + -20 Reorder the terms: 20 + -20 + 15x2 + x4 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + 15x2 + x4 = 0 + -20 15x2 + x4 = 0 + -20 Combine like terms: 0 + -20 = -20 15x2 + x4 = -20 The x term is 15x2. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15x2 + 56.25 + x4 = -20 + 56.25 Reorder the terms: 56.25 + 15x2 + x4 = -20 + 56.25 Combine like terms: -20 + 56.25 = 36.25 56.25 + 15x2 + x4 = 36.25 Factor a perfect square on the left side: (x2 + 7.5)(x2 + 7.5) = 36.25 Calculate the square root of the right side: 6.020797289 Break this problem into two subproblems by setting (x2 + 7.5) equal to 6.020797289 and -6.020797289.Subproblem 1
