Simplifying m2 + 10m + 74 = 0 Reorder the terms: 74 + 10m + m2 = 0 Solving 74 + 10m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '-74' to each side of the equation. 74 + 10m + -74 + m2 = 0 + -74 Reorder the terms: 74 + -74 + 10m + m2 = 0 + -74 Combine like terms: 74 + -74 = 0 0 + 10m + m2 = 0 + -74 10m + m2 = 0 + -74 Combine like terms: 0 + -74 = -74 10m + m2 = -74 The m term is 10m. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10m + 25 + m2 = -74 + 25 Reorder the terms: 25 + 10m + m2 = -74 + 25 Combine like terms: -74 + 25 = -49 25 + 10m + m2 = -49 Factor a perfect square on the left side: (m + 5)(m + 5) = -49 Can't calculate square root of the right side. The solution to this equation could not be determined.
