Simplifying 2d2 + -5d + -6 = 0 Reorder the terms: -6 + -5d + 2d2 = 0 Solving -6 + -5d + 2d2 = 0 Solving for variable 'd'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -3 + -2.5d + d2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -2.5d + 3 + d2 = 0 + 3 Reorder the terms: -3 + 3 + -2.5d + d2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -2.5d + d2 = 0 + 3 -2.5d + d2 = 0 + 3 Combine like terms: 0 + 3 = 3 -2.5d + d2 = 3 The d term is -2.5d. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5d + 1.5625 + d2 = 3 + 1.5625 Reorder the terms: 1.5625 + -2.5d + d2 = 3 + 1.5625 Combine like terms: 3 + 1.5625 = 4.5625 1.5625 + -2.5d + d2 = 4.5625 Factor a perfect square on the left side: (d + -1.25)(d + -1.25) = 4.5625 Calculate the square root of the right side: 2.136000936 Break this problem into two subproblems by setting (d + -1.25) equal to 2.136000936 and -2.136000936.Subproblem 1
d + -1.25 = 2.136000936 Simplifying d + -1.25 = 2.136000936 Reorder the terms: -1.25 + d = 2.136000936 Solving -1.25 + d = 2.136000936 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + d = 2.136000936 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + d = 2.136000936 + 1.25 d = 2.136000936 + 1.25 Combine like terms: 2.136000936 + 1.25 = 3.386000936 d = 3.386000936 Simplifying d = 3.386000936Subproblem 2
d + -1.25 = -2.136000936 Simplifying d + -1.25 = -2.136000936 Reorder the terms: -1.25 + d = -2.136000936 Solving -1.25 + d = -2.136000936 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + d = -2.136000936 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + d = -2.136000936 + 1.25 d = -2.136000936 + 1.25 Combine like terms: -2.136000936 + 1.25 = -0.886000936 d = -0.886000936 Simplifying d = -0.886000936Solution
The solution to the problem is based on the solutions from the subproblems. d = {3.386000936, -0.886000936}
