Subproblem 1

Set the factor '(8 + 7m + 2m2)' equal to zero and attempt to solve: Simplifying 8 + 7m + 2m2 = 0 Solving 8 + 7m + 2m2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4 + 3.5m + m2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + 3.5m + -4 + m2 = 0 + -4 Reorder the terms: 4 + -4 + 3.5m + m2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 3.5m + m2 = 0 + -4 3.5m + m2 = 0 + -4 Combine like terms: 0 + -4 = -4 3.5m + m2 = -4 The m term is 3.5m. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5m + 3.0625 + m2 = -4 + 3.0625 Reorder the terms: 3.0625 + 3.5m + m2 = -4 + 3.0625 Combine like terms: -4 + 3.0625 = -0.9375 3.0625 + 3.5m + m2 = -0.9375 Factor a perfect square on the left side: (m + 1.75)(m + 1.75) = -0.9375 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.
