Subproblem 1

Set the factor '(-49 + 24d + d2)' equal to zero and attempt to solve: Simplifying -49 + 24d + d2 = 0 Solving -49 + 24d + d2 = 0 Begin completing the square. Move the constant term to the right: Add '49' to each side of the equation. -49 + 24d + 49 + d2 = 0 + 49 Reorder the terms: -49 + 49 + 24d + d2 = 0 + 49 Combine like terms: -49 + 49 = 0 0 + 24d + d2 = 0 + 49 24d + d2 = 0 + 49 Combine like terms: 0 + 49 = 49 24d + d2 = 49 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 = 49 + 144 Reorder the terms: 144 + 24d + d2 = 49 + 144 Combine like terms: 49 + 144 = 193 144 + 24d + d2 = 193 Factor a perfect square on the left side: (d + 12)(d + 12) = 193 Calculate the square root of the right side: 13.892443989 Break this problem into two subproblems by setting (d + 12) equal to 13.892443989 and -13.892443989.

Subproblem 1

d + 12 = 13.892443989 Simplifying d + 12 = 13.892443989 Reorder the terms: 12 + d = 13.892443989 Solving 12 + d = 13.892443989 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 = 13.892443989 + -12 Combine like terms: 12 + -12 = 0 0 + d = 13.892443989 + -12 d = 13.892443989 + -12 Combine like terms: 13.892443989 + -12 = 1.892443989 d = 1.892443989 Simplifying d = 1.892443989

Subproblem 2

d + 12 = -13.892443989 Simplifying d + 12 = -13.892443989 Reorder the terms: 12 + d = -13.892443989 Solving 12 + d = -13.892443989 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 = -13.892443989 + -12 Combine like terms: 12 + -12 = 0 0 + d = -13.892443989 + -12 d = -13.892443989 + -12 Combine like terms: -13.892443989 + -12 = -25.892443989 d = -25.892443989 Simplifying d = -25.892443989
