Simplifying 2x2 + 31x + -6.7 = 0 Reorder the terms: -6.7 + 31x + 2x2 = 0 Solving -6.7 + 31x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -3.35 + 15.5x + x2 = 0 Move the constant term to the right: Add '3.35' to each side of the equation. -3.35 + 15.5x + 3.35 + x2 = 0 + 3.35 Reorder the terms: -3.35 + 3.35 + 15.5x + x2 = 0 + 3.35 Combine like terms: -3.35 + 3.35 = 0.00 0.00 + 15.5x + x2 = 0 + 3.35 15.5x + x2 = 0 + 3.35 Combine like terms: 0 + 3.35 = 3.35 15.5x + x2 = 3.35 The x term is 15.5x. Take half its coefficient (7.75). Square it (60.0625) and add it to both sides. Add '60.0625' to each side of the equation. 15.5x + 60.0625 + x2 = 3.35 + 60.0625 Reorder the terms: 60.0625 + 15.5x + x2 = 3.35 + 60.0625 Combine like terms: 3.35 + 60.0625 = 63.4125 60.0625 + 15.5x + x2 = 63.4125 Factor a perfect square on the left side: (x + 7.75)(x + 7.75) = 63.4125 Calculate the square root of the right side: 7.963196594 Break this problem into two subproblems by setting (x + 7.75) equal to 7.963196594 and -7.963196594.Subproblem 1
x + 7.75 = 7.963196594 Simplifying x + 7.75 = 7.963196594 Reorder the terms: 7.75 + x = 7.963196594 Solving 7.75 + x = 7.963196594 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.75' to each side of the equation. 7.75 + -7.75 + x = 7.963196594 + -7.75 Combine like terms: 7.75 + -7.75 = 0.00 0.00 + x = 7.963196594 + -7.75 x = 7.963196594 + -7.75 Combine like terms: 7.963196594 + -7.75 = 0.213196594 x = 0.213196594 Simplifying x = 0.213196594Subproblem 2
x + 7.75 = -7.963196594 Simplifying x + 7.75 = -7.963196594 Reorder the terms: 7.75 + x = -7.963196594 Solving 7.75 + x = -7.963196594 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.75' to each side of the equation. 7.75 + -7.75 + x = -7.963196594 + -7.75 Combine like terms: 7.75 + -7.75 = 0.00 0.00 + x = -7.963196594 + -7.75 x = -7.963196594 + -7.75 Combine like terms: -7.963196594 + -7.75 = -15.713196594 x = -15.713196594 Simplifying x = -15.713196594Solution
