Simplifying n2 + 3n + 12 = 0 Reorder the terms: 12 + 3n + n2 = 0 Solving 12 + 3n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '-12' to each side of the equation. 12 + 3n + -12 + n2 = 0 + -12 Reorder the terms: 12 + -12 + 3n + n2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + 3n + n2 = 0 + -12 3n + n2 = 0 + -12 Combine like terms: 0 + -12 = -12 3n + n2 = -12 The n term is 3n. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3n + 2.25 + n2 = -12 + 2.25 Reorder the terms: 2.25 + 3n + n2 = -12 + 2.25 Combine like terms: -12 + 2.25 = -9.75 2.25 + 3n + n2 = -9.75 Factor a perfect square on the left side: (n + 1.5)(n + 1.5) = -9.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
