Simplifying 20d2 + 23d + -23 = 0 Reorder the terms: -23 + 23d + 20d2 = 0 Solving -23 + 23d + 20d2 = 0 Solving for variable 'd'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -1.15 + 1.15d + d2 = 0 Move the constant term to the right: Add '1.15' to each side of the equation. -1.15 + 1.15d + 1.15 + d2 = 0 + 1.15 Reorder the terms: -1.15 + 1.15 + 1.15d + d2 = 0 + 1.15 Combine like terms: -1.15 + 1.15 = 0.00 0.00 + 1.15d + d2 = 0 + 1.15 1.15d + d2 = 0 + 1.15 Combine like terms: 0 + 1.15 = 1.15 1.15d + d2 = 1.15 The d term is 1.15d. Take half its coefficient (0.575). Square it (0.330625) and add it to both sides. Add '0.330625' to each side of the equation. 1.15d + 0.330625 + d2 = 1.15 + 0.330625 Reorder the terms: 0.330625 + 1.15d + d2 = 1.15 + 0.330625 Combine like terms: 1.15 + 0.330625 = 1.480625 0.330625 + 1.15d + d2 = 1.480625 Factor a perfect square on the left side: (d + 0.575)(d + 0.575) = 1.480625 Calculate the square root of the right side: 1.216809352 Break this problem into two subproblems by setting (d + 0.575) equal to 1.216809352 and -1.216809352.Subproblem 1
d + 0.575 = 1.216809352 Simplifying d + 0.575 = 1.216809352 Reorder the terms: 0.575 + d = 1.216809352 Solving 0.575 + d = 1.216809352 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-0.575' to each side of the equation. 0.575 + -0.575 + d = 1.216809352 + -0.575 Combine like terms: 0.575 + -0.575 = 0.000 0.000 + d = 1.216809352 + -0.575 d = 1.216809352 + -0.575 Combine like terms: 1.216809352 + -0.575 = 0.641809352 d = 0.641809352 Simplifying d = 0.641809352Subproblem 2
d + 0.575 = -1.216809352 Simplifying d + 0.575 = -1.216809352 Reorder the terms: 0.575 + d = -1.216809352 Solving 0.575 + d = -1.216809352 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-0.575' to each side of the equation. 0.575 + -0.575 + d = -1.216809352 + -0.575 Combine like terms: 0.575 + -0.575 = 0.000 0.000 + d = -1.216809352 + -0.575 d = -1.216809352 + -0.575 Combine like terms: -1.216809352 + -0.575 = -1.791809352 d = -1.791809352 Simplifying d = -1.791809352Solution
The solution to the problem is based on the solutions from the subproblems. d = {0.641809352, -1.791809352}
