Simplifying n2 + 18n + 85 = 0 Reorder the terms: 85 + 18n + n2 = 0 Solving 85 + 18n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '-85' to each side of the equation. 85 + 18n + -85 + n2 = 0 + -85 Reorder the terms: 85 + -85 + 18n + n2 = 0 + -85 Combine like terms: 85 + -85 = 0 0 + 18n + n2 = 0 + -85 18n + n2 = 0 + -85 Combine like terms: 0 + -85 = -85 18n + n2 = -85 The n term is 18n. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18n + 81 + n2 = -85 + 81 Reorder the terms: 81 + 18n + n2 = -85 + 81 Combine like terms: -85 + 81 = -4 81 + 18n + n2 = -4 Factor a perfect square on the left side: (n + 9)(n + 9) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
