Subproblem 1

Set the factor '(2 + d + d2)' equal to zero and attempt to solve: Simplifying 2 + d + d2 = 0 Solving 2 + d + d2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + d + -2 + d2 = 0 + -2 Reorder the terms: 2 + -2 + d + d2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + d + d2 = 0 + -2 d + d2 = 0 + -2 Combine like terms: 0 + -2 = -2 d + d2 = -2 The d term is d. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. d + 0.25 + d2 = -2 + 0.25 Reorder the terms: 0.25 + d + d2 = -2 + 0.25 Combine like terms: -2 + 0.25 = -1.75 0.25 + d + d2 = -1.75 Factor a perfect square on the left side: (d + 0.5)(d + 0.5) = -1.75 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
