Simplifying 8x2 + -40x + -679 = 0 Reorder the terms: -679 + -40x + 8x2 = 0 Solving -679 + -40x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -84.875 + -5x + x2 = 0 Move the constant term to the right: Add '84.875' to each side of the equation. -84.875 + -5x + 84.875 + x2 = 0 + 84.875 Reorder the terms: -84.875 + 84.875 + -5x + x2 = 0 + 84.875 Combine like terms: -84.875 + 84.875 = 0.000 0.000 + -5x + x2 = 0 + 84.875 -5x + x2 = 0 + 84.875 Combine like terms: 0 + 84.875 = 84.875 -5x + x2 = 84.875 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 84.875 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 84.875 + 6.25 Combine like terms: 84.875 + 6.25 = 91.125 6.25 + -5x + x2 = 91.125 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 91.125 Calculate the square root of the right side: 9.545941546 Break this problem into two subproblems by setting (x + -2.5) equal to 9.545941546 and -9.545941546.Subproblem 1
x + -2.5 = 9.545941546 Simplifying x + -2.5 = 9.545941546 Reorder the terms: -2.5 + x = 9.545941546 Solving -2.5 + x = 9.545941546 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 9.545941546 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 9.545941546 + 2.5 x = 9.545941546 + 2.5 Combine like terms: 9.545941546 + 2.5 = 12.045941546 x = 12.045941546 Simplifying x = 12.045941546Subproblem 2
x + -2.5 = -9.545941546 Simplifying x + -2.5 = -9.545941546 Reorder the terms: -2.5 + x = -9.545941546 Solving -2.5 + x = -9.545941546 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -9.545941546 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -9.545941546 + 2.5 x = -9.545941546 + 2.5 Combine like terms: -9.545941546 + 2.5 = -7.045941546 x = -7.045941546 Simplifying x = -7.045941546Solution
