Simplifying d2 + 20d = -7 Reorder the terms: 20d + d2 = -7 Solving 20d + d2 = -7 Solving for variable 'd'. Reorder the terms: 7 + 20d + d2 = -7 + 7 Combine like terms: -7 + 7 = 0 7 + 20d + d2 = 0 Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + 20d + -7 + d2 = 0 + -7 Reorder the terms: 7 + -7 + 20d + d2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 20d + d2 = 0 + -7 20d + d2 = 0 + -7 Combine like terms: 0 + -7 = -7 20d + d2 = -7 The d term is 20d. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20d + 100 + d2 = -7 + 100 Reorder the terms: 100 + 20d + d2 = -7 + 100 Combine like terms: -7 + 100 = 93 100 + 20d + d2 = 93 Factor a perfect square on the left side: (d + 10)(d + 10) = 93 Calculate the square root of the right side: 9.643650761 Break this problem into two subproblems by setting (d + 10) equal to 9.643650761 and -9.643650761.Subproblem 1
d + 10 = 9.643650761 Simplifying d + 10 = 9.643650761 Reorder the terms: 10 + d = 9.643650761 Solving 10 + d = 9.643650761 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + d = 9.643650761 + -10 Combine like terms: 10 + -10 = 0 0 + d = 9.643650761 + -10 d = 9.643650761 + -10 Combine like terms: 9.643650761 + -10 = -0.356349239 d = -0.356349239 Simplifying d = -0.356349239Subproblem 2
d + 10 = -9.643650761 Simplifying d + 10 = -9.643650761 Reorder the terms: 10 + d = -9.643650761 Solving 10 + d = -9.643650761 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + d = -9.643650761 + -10 Combine like terms: 10 + -10 = 0 0 + d = -9.643650761 + -10 d = -9.643650761 + -10 Combine like terms: -9.643650761 + -10 = -19.643650761 d = -19.643650761 Simplifying d = -19.643650761Solution
The solution to the problem is based on the solutions from the subproblems. d = {-0.356349239, -19.643650761}
