Simplifying m2 + 2.2m + 117 = 0 Reorder the terms: 117 + 2.2m + m2 = 0 Solving 117 + 2.2m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '-117' to each side of the equation. 117 + 2.2m + -117 + m2 = 0 + -117 Reorder the terms: 117 + -117 + 2.2m + m2 = 0 + -117 Combine like terms: 117 + -117 = 0 0 + 2.2m + m2 = 0 + -117 2.2m + m2 = 0 + -117 Combine like terms: 0 + -117 = -117 2.2m + m2 = -117 The m term is 2.2m. Take half its coefficient (1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. 2.2m + 1.21 + m2 = -117 + 1.21 Reorder the terms: 1.21 + 2.2m + m2 = -117 + 1.21 Combine like terms: -117 + 1.21 = -115.79 1.21 + 2.2m + m2 = -115.79 Factor a perfect square on the left side: (m + 1.1)(m + 1.1) = -115.79 Can't calculate square root of the right side. The solution to this equation could not be determined.
