Simplifying 8x6 + 4x4 + -2x2 = 0 Reorder the terms: -2x2 + 4x4 + 8x6 = 0 Solving -2x2 + 4x4 + 8x6 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x2'. 2x2(-1 + 2x2 + 4x4) = 0 Ignore the factor 2.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 '(-1 + 2x2 + 4x4)' equal to zero and attempt to solve: Simplifying -1 + 2x2 + 4x4 = 0 Solving -1 + 2x2 + 4x4 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.25 + 0.5x2 + x4 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + 0.5x2 + 0.25 + x4 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + 0.5x2 + x4 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + 0.5x2 + x4 = 0 + 0.25 0.5x2 + x4 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 0.5x2 + x4 = 0.25 The x term is 0.5x2. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x2 + 0.0625 + x4 = 0.25 + 0.0625 Reorder the terms: 0.0625 + 0.5x2 + x4 = 0.25 + 0.0625 Combine like terms: 0.25 + 0.0625 = 0.3125 0.0625 + 0.5x2 + x4 = 0.3125 Factor a perfect square on the left side: (x2 + 0.25)(x2 + 0.25) = 0.3125 Calculate the square root of the right side: 0.559016994 Break this problem into two subproblems by setting (x2 + 0.25) equal to 0.559016994 and -0.559016994.Subproblem 1
x2 + 0.25 = 0.559016994 Simplifying x2 + 0.25 = 0.559016994 Reorder the terms: 0.25 + x2 = 0.559016994 Solving 0.25 + x2 = 0.559016994 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x2 = 0.559016994 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x2 = 0.559016994 + -0.25 x2 = 0.559016994 + -0.25 Combine like terms: 0.559016994 + -0.25 = 0.309016994 x2 = 0.309016994 Simplifying x2 = 0.309016994 Take the square root of each side: x = {-0.55589297, 0.55589297}Subproblem 2
x2 + 0.25 = -0.559016994 Simplifying x2 + 0.25 = -0.559016994 Reorder the terms: 0.25 + x2 = -0.559016994 Solving 0.25 + x2 = -0.559016994 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
