Subproblem 1

Set the factor '(-7 + 3v + -12v2)' equal to zero and attempt to solve: Simplifying -7 + 3v + -12v2 = 0 Solving -7 + 3v + -12v2 = 0 Begin completing the square. Divide all terms by -12 the coefficient of the squared term: Divide each side by '-12'. 0.5833333333 + -0.25v + v2 = 0 Move the constant term to the right: Add '-0.5833333333' to each side of the equation. 0.5833333333 + -0.25v + -0.5833333333 + v2 = 0 + -0.5833333333 Reorder the terms: 0.5833333333 + -0.5833333333 + -0.25v + v2 = 0 + -0.5833333333 Combine like terms: 0.5833333333 + -0.5833333333 = 0.0000000000 0.0000000000 + -0.25v + v2 = 0 + -0.5833333333 -0.25v + v2 = 0 + -0.5833333333 Combine like terms: 0 + -0.5833333333 = -0.5833333333 -0.25v + v2 = -0.5833333333 The v term is -0.25v. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25v + 0.015625 + v2 = -0.5833333333 + 0.015625 Reorder the terms: 0.015625 + -0.25v + v2 = -0.5833333333 + 0.015625 Combine like terms: -0.5833333333 + 0.015625 = -0.5677083333 0.015625 + -0.25v + v2 = -0.5677083333 Factor a perfect square on the left side: (v + -0.125)(v + -0.125) = -0.5677083333 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.
