Simplifying 2x2 + 13x + -140 = 0 Reorder the terms: -140 + 13x + 2x2 = 0 Solving -140 + 13x + 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'. -70 + 6.5x + x2 = 0 Move the constant term to the right: Add '70' to each side of the equation. -70 + 6.5x + 70 + x2 = 0 + 70 Reorder the terms: -70 + 70 + 6.5x + x2 = 0 + 70 Combine like terms: -70 + 70 = 0 0 + 6.5x + x2 = 0 + 70 6.5x + x2 = 0 + 70 Combine like terms: 0 + 70 = 70 6.5x + x2 = 70 The x term is 6.5x. Take half its coefficient (3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. 6.5x + 10.5625 + x2 = 70 + 10.5625 Reorder the terms: 10.5625 + 6.5x + x2 = 70 + 10.5625 Combine like terms: 70 + 10.5625 = 80.5625 10.5625 + 6.5x + x2 = 80.5625 Factor a perfect square on the left side: (x + 3.25)(x + 3.25) = 80.5625 Calculate the square root of the right side: 8.975661536 Break this problem into two subproblems by setting (x + 3.25) equal to 8.975661536 and -8.975661536.Subproblem 1
x + 3.25 = 8.975661536 Simplifying x + 3.25 = 8.975661536 Reorder the terms: 3.25 + x = 8.975661536 Solving 3.25 + x = 8.975661536 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = 8.975661536 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = 8.975661536 + -3.25 x = 8.975661536 + -3.25 Combine like terms: 8.975661536 + -3.25 = 5.725661536 x = 5.725661536 Simplifying x = 5.725661536Subproblem 2
x + 3.25 = -8.975661536 Simplifying x + 3.25 = -8.975661536 Reorder the terms: 3.25 + x = -8.975661536 Solving 3.25 + x = -8.975661536 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = -8.975661536 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = -8.975661536 + -3.25 x = -8.975661536 + -3.25 Combine like terms: -8.975661536 + -3.25 = -12.225661536 x = -12.225661536 Simplifying x = -12.225661536Solution
