Simplifying n2 + 15n + 57 = 0 Reorder the terms: 57 + 15n + n2 = 0 Solving 57 + 15n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '-57' to each side of the equation. 57 + 15n + -57 + n2 = 0 + -57 Reorder the terms: 57 + -57 + 15n + n2 = 0 + -57 Combine like terms: 57 + -57 = 0 0 + 15n + n2 = 0 + -57 15n + n2 = 0 + -57 Combine like terms: 0 + -57 = -57 15n + n2 = -57 The n term is 15n. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15n + 56.25 + n2 = -57 + 56.25 Reorder the terms: 56.25 + 15n + n2 = -57 + 56.25 Combine like terms: -57 + 56.25 = -0.75 56.25 + 15n + n2 = -0.75 Factor a perfect square on the left side: (n + 7.5)(n + 7.5) = -0.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
