Simplifying m2 + -5m + 16 = 0 Reorder the terms: 16 + -5m + m2 = 0 Solving 16 + -5m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -5m + -16 + m2 = 0 + -16 Reorder the terms: 16 + -16 + -5m + m2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -5m + m2 = 0 + -16 -5m + m2 = 0 + -16 Combine like terms: 0 + -16 = -16 -5m + m2 = -16 The m term is -5m. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5m + 6.25 + m2 = -16 + 6.25 Reorder the terms: 6.25 + -5m + m2 = -16 + 6.25 Combine like terms: -16 + 6.25 = -9.75 6.25 + -5m + m2 = -9.75 Factor a perfect square on the left side: (m + -2.5)(m + -2.5) = -9.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
