Simplifying x = 8x2 + 12x + -20 Reorder the terms: x = -20 + 12x + 8x2 Solving x = -20 + 12x + 8x2 Solving for variable 'x'. Reorder the terms: 20 + x + -12x + -8x2 = -20 + 12x + 8x2 + 20 + -12x + -8x2 Combine like terms: x + -12x = -11x 20 + -11x + -8x2 = -20 + 12x + 8x2 + 20 + -12x + -8x2 Reorder the terms: 20 + -11x + -8x2 = -20 + 20 + 12x + -12x + 8x2 + -8x2 Combine like terms: -20 + 20 = 0 20 + -11x + -8x2 = 0 + 12x + -12x + 8x2 + -8x2 20 + -11x + -8x2 = 12x + -12x + 8x2 + -8x2 Combine like terms: 12x + -12x = 0 20 + -11x + -8x2 = 0 + 8x2 + -8x2 20 + -11x + -8x2 = 8x2 + -8x2 Combine like terms: 8x2 + -8x2 = 0 20 + -11x + -8x2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -2.5 + 1.375x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 1.375x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 1.375x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 1.375x + x2 = 0 + 2.5 1.375x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 1.375x + x2 = 2.5 The x term is 1.375x. Take half its coefficient (0.6875). Square it (0.47265625) and add it to both sides. Add '0.47265625' to each side of the equation. 1.375x + 0.47265625 + x2 = 2.5 + 0.47265625 Reorder the terms: 0.47265625 + 1.375x + x2 = 2.5 + 0.47265625 Combine like terms: 2.5 + 0.47265625 = 2.97265625 0.47265625 + 1.375x + x2 = 2.97265625 Factor a perfect square on the left side: (x + 0.6875)(x + 0.6875) = 2.97265625 Calculate the square root of the right side: 1.724139278 Break this problem into two subproblems by setting (x + 0.6875) equal to 1.724139278 and -1.724139278.Subproblem 1
x + 0.6875 = 1.724139278 Simplifying x + 0.6875 = 1.724139278 Reorder the terms: 0.6875 + x = 1.724139278 Solving 0.6875 + x = 1.724139278 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.6875' to each side of the equation. 0.6875 + -0.6875 + x = 1.724139278 + -0.6875 Combine like terms: 0.6875 + -0.6875 = 0.0000 0.0000 + x = 1.724139278 + -0.6875 x = 1.724139278 + -0.6875 Combine like terms: 1.724139278 + -0.6875 = 1.036639278 x = 1.036639278 Simplifying x = 1.036639278Subproblem 2
x + 0.6875 = -1.724139278 Simplifying x + 0.6875 = -1.724139278 Reorder the terms: 0.6875 + x = -1.724139278 Solving 0.6875 + x = -1.724139278 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.6875' to each side of the equation. 0.6875 + -0.6875 + x = -1.724139278 + -0.6875 Combine like terms: 0.6875 + -0.6875 = 0.0000 0.0000 + x = -1.724139278 + -0.6875 x = -1.724139278 + -0.6875 Combine like terms: -1.724139278 + -0.6875 = -2.411639278 x = -2.411639278 Simplifying x = -2.411639278Solution
