Subproblem 1

Set the factor '(2 + 2m + m2)' equal to zero and attempt to solve: Simplifying 2 + 2m + m2 = 0 Solving 2 + 2m + m2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 2m + -2 + m2 = 0 + -2 Reorder the terms: 2 + -2 + 2m + m2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 2m + m2 = 0 + -2 2m + m2 = 0 + -2 Combine like terms: 0 + -2 = -2 2m + m2 = -2 The m term is 2m. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2m + 1 + m2 = -2 + 1 Reorder the terms: 1 + 2m + m2 = -2 + 1 Combine like terms: -2 + 1 = -1 1 + 2m + m2 = -1 Factor a perfect square on the left side: (m + 1)(m + 1) = -1 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.
