Simplifying 3 + -7m = -8m2 Solving 3 + -7m = -8m2 Solving for variable 'm'. Combine like terms: -8m2 + 8m2 = 0 3 + -7m + 8m2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.375 + -0.875m + m2 = 0 Move the constant term to the right: Add '-0.375' to each side of the equation. 0.375 + -0.875m + -0.375 + m2 = 0 + -0.375 Reorder the terms: 0.375 + -0.375 + -0.875m + m2 = 0 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + -0.875m + m2 = 0 + -0.375 -0.875m + m2 = 0 + -0.375 Combine like terms: 0 + -0.375 = -0.375 -0.875m + m2 = -0.375 The m term is -0.875m. Take half its coefficient (-0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. -0.875m + 0.19140625 + m2 = -0.375 + 0.19140625 Reorder the terms: 0.19140625 + -0.875m + m2 = -0.375 + 0.19140625 Combine like terms: -0.375 + 0.19140625 = -0.18359375 0.19140625 + -0.875m + m2 = -0.18359375 Factor a perfect square on the left side: (m + -0.4375)(m + -0.4375) = -0.18359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
