Subproblem 1

Set the factor '(1 + -1v + v2)' equal to zero and attempt to solve: Simplifying 1 + -1v + v2 = 0 Solving 1 + -1v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + -1v + -1 + v2 = 0 + -1 Reorder the terms: 1 + -1 + -1v + v2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1v + v2 = 0 + -1 -1v + v2 = 0 + -1 Combine like terms: 0 + -1 = -1 -1v + v2 = -1 The v term is -1v. 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. -1v + 0.25 + v2 = -1 + 0.25 Reorder the terms: 0.25 + -1v + v2 = -1 + 0.25 Combine like terms: -1 + 0.25 = -0.75 0.25 + -1v + v2 = -0.75 Factor a perfect square on the left side: (v + -0.5)(v + -0.5) = -0.75 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.
