Simplifying d2 + 24d + 7 = 0 Reorder the terms: 7 + 24d + d2 = 0 Solving 7 + 24d + d2 = 0 Solving for variable 'd'. Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + 24d + -7 + d2 = 0 + -7 Reorder the terms: 7 + -7 + 24d + d2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 24d + d2 = 0 + -7 24d + d2 = 0 + -7 Combine like terms: 0 + -7 = -7 24d + d2 = -7 The d term is 24d. Take half its coefficient (12). Square it (144) and add it to both sides. Add '144' to each side of the equation. 24d + 144 + d2 = -7 + 144 Reorder the terms: 144 + 24d + d2 = -7 + 144 Combine like terms: -7 + 144 = 137 144 + 24d + d2 = 137 Factor a perfect square on the left side: (d + 12)(d + 12) = 137 Calculate the square root of the right side: 11.704699911 Break this problem into two subproblems by setting (d + 12) equal to 11.704699911 and -11.704699911.Subproblem 1
d + 12 = 11.704699911 Simplifying d + 12 = 11.704699911 Reorder the terms: 12 + d = 11.704699911 Solving 12 + d = 11.704699911 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + d = 11.704699911 + -12 Combine like terms: 12 + -12 = 0 0 + d = 11.704699911 + -12 d = 11.704699911 + -12 Combine like terms: 11.704699911 + -12 = -0.295300089 d = -0.295300089 Simplifying d = -0.295300089Subproblem 2
d + 12 = -11.704699911 Simplifying d + 12 = -11.704699911 Reorder the terms: 12 + d = -11.704699911 Solving 12 + d = -11.704699911 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + d = -11.704699911 + -12 Combine like terms: 12 + -12 = 0 0 + d = -11.704699911 + -12 d = -11.704699911 + -12 Combine like terms: -11.704699911 + -12 = -23.704699911 d = -23.704699911 Simplifying d = -23.704699911Solution
The solution to the problem is based on the solutions from the subproblems. d = {-0.295300089, -23.704699911}
