Simplifying m2 + -12m + 140 = 0 Reorder the terms: 140 + -12m + m2 = 0 Solving 140 + -12m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '-140' to each side of the equation. 140 + -12m + -140 + m2 = 0 + -140 Reorder the terms: 140 + -140 + -12m + m2 = 0 + -140 Combine like terms: 140 + -140 = 0 0 + -12m + m2 = 0 + -140 -12m + m2 = 0 + -140 Combine like terms: 0 + -140 = -140 -12m + m2 = -140 The m term is -12m. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12m + 36 + m2 = -140 + 36 Reorder the terms: 36 + -12m + m2 = -140 + 36 Combine like terms: -140 + 36 = -104 36 + -12m + m2 = -104 Factor a perfect square on the left side: (m + -6)(m + -6) = -104 Can't calculate square root of the right side. The solution to this equation could not be determined.
