Subproblem 1

Set the factor '(3 + 2D + D2)' equal to zero and attempt to solve: Simplifying 3 + 2D + D2 = 0 Solving 3 + 2D + D2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 2D + -3 + D2 = 0 + -3 Reorder the terms: 3 + -3 + 2D + D2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2D + D2 = 0 + -3 2D + D2 = 0 + -3 Combine like terms: 0 + -3 = -3 2D + D2 = -3 The D term is 2D. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2D + 1 + D2 = -3 + 1 Reorder the terms: 1 + 2D + D2 = -3 + 1 Combine like terms: -3 + 1 = -2 1 + 2D + D2 = -2 Factor a perfect square on the left side: (D + 1)(D + 1) = -2 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.
