Simplifying m = -4m2 + -7m + -8 Reorder the terms: m = -8 + -7m + -4m2 Solving m = -8 + -7m + -4m2 Solving for variable 'm'. Reorder the terms: 8 + m + 7m + 4m2 = -8 + -7m + -4m2 + 8 + 7m + 4m2 Combine like terms: m + 7m = 8m 8 + 8m + 4m2 = -8 + -7m + -4m2 + 8 + 7m + 4m2 Reorder the terms: 8 + 8m + 4m2 = -8 + 8 + -7m + 7m + -4m2 + 4m2 Combine like terms: -8 + 8 = 0 8 + 8m + 4m2 = 0 + -7m + 7m + -4m2 + 4m2 8 + 8m + 4m2 = -7m + 7m + -4m2 + 4m2 Combine like terms: -7m + 7m = 0 8 + 8m + 4m2 = 0 + -4m2 + 4m2 8 + 8m + 4m2 = -4m2 + 4m2 Combine like terms: -4m2 + 4m2 = 0 8 + 8m + 4m2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(2 + 2m + m2) = 0 Ignore the factor 4.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.
