Simplifying 4x4 + -1x2 + -6 = 0 Reorder the terms: -6 + -1x2 + 4x4 = 0 Solving -6 + -1x2 + 4x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.5 + -0.25x2 + x4 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -0.25x2 + 1.5 + x4 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -0.25x2 + x4 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -0.25x2 + x4 = 0 + 1.5 -0.25x2 + x4 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -0.25x2 + x4 = 1.5 The x term is -0.25x2. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x2 + 0.015625 + x4 = 1.5 + 0.015625 Reorder the terms: 0.015625 + -0.25x2 + x4 = 1.5 + 0.015625 Combine like terms: 1.5 + 0.015625 = 1.515625 0.015625 + -0.25x2 + x4 = 1.515625 Factor a perfect square on the left side: (x2 + -0.125)(x2 + -0.125) = 1.515625 Calculate the square root of the right side: 1.231107225 Break this problem into two subproblems by setting (x2 + -0.125) equal to 1.231107225 and -1.231107225.Subproblem 1
x2 + -0.125 = 1.231107225 Simplifying x2 + -0.125 = 1.231107225 Reorder the terms: -0.125 + x2 = 1.231107225 Solving -0.125 + x2 = 1.231107225 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x2 = 1.231107225 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x2 = 1.231107225 + 0.125 x2 = 1.231107225 + 0.125 Combine like terms: 1.231107225 + 0.125 = 1.356107225 x2 = 1.356107225 Simplifying x2 = 1.356107225 Take the square root of each side: x = {-1.164520169, 1.164520169}Subproblem 2
x2 + -0.125 = -1.231107225 Simplifying x2 + -0.125 = -1.231107225 Reorder the terms: -0.125 + x2 = -1.231107225 Solving -0.125 + x2 = -1.231107225 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
