Simplifying 4x2 + -1x + -3 = 315 Reorder the terms: -3 + -1x + 4x2 = 315 Solving -3 + -1x + 4x2 = 315 Solving for variable 'x'. Reorder the terms: -3 + -315 + -1x + 4x2 = 315 + -315 Combine like terms: -3 + -315 = -318 -318 + -1x + 4x2 = 315 + -315 Combine like terms: 315 + -315 = 0 -318 + -1x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -79.5 + -0.25x + x2 = 0 Move the constant term to the right: Add '79.5' to each side of the equation. -79.5 + -0.25x + 79.5 + x2 = 0 + 79.5 Reorder the terms: -79.5 + 79.5 + -0.25x + x2 = 0 + 79.5 Combine like terms: -79.5 + 79.5 = 0.0 0.0 + -0.25x + x2 = 0 + 79.5 -0.25x + x2 = 0 + 79.5 Combine like terms: 0 + 79.5 = 79.5 -0.25x + x2 = 79.5 The x term is -0.25x. 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. -0.25x + 0.015625 + x2 = 79.5 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 79.5 + 0.015625 Combine like terms: 79.5 + 0.015625 = 79.515625 0.015625 + -0.25x + x2 = 79.515625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 79.515625 Calculate the square root of the right side: 8.917153414 Break this problem into two subproblems by setting (x + -0.125) equal to 8.917153414 and -8.917153414.Subproblem 1
x + -0.125 = 8.917153414 Simplifying x + -0.125 = 8.917153414 Reorder the terms: -0.125 + x = 8.917153414 Solving -0.125 + x = 8.917153414 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 + x = 8.917153414 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 8.917153414 + 0.125 x = 8.917153414 + 0.125 Combine like terms: 8.917153414 + 0.125 = 9.042153414 x = 9.042153414 Simplifying x = 9.042153414Subproblem 2
x + -0.125 = -8.917153414 Simplifying x + -0.125 = -8.917153414 Reorder the terms: -0.125 + x = -8.917153414 Solving -0.125 + x = -8.917153414 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 + x = -8.917153414 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = -8.917153414 + 0.125 x = -8.917153414 + 0.125 Combine like terms: -8.917153414 + 0.125 = -8.792153414 x = -8.792153414 Simplifying x = -8.792153414Solution
