Simplifying u2 + u + 18 = 0 Reorder the terms: 18 + u + u2 = 0 Solving 18 + u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + u + -18 + u2 = 0 + -18 Reorder the terms: 18 + -18 + u + u2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + u + u2 = 0 + -18 u + u2 = 0 + -18 Combine like terms: 0 + -18 = -18 u + u2 = -18 The u term is u. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. u + 0.25 + u2 = -18 + 0.25 Reorder the terms: 0.25 + u + u2 = -18 + 0.25 Combine like terms: -18 + 0.25 = -17.75 0.25 + u + u2 = -17.75 Factor a perfect square on the left side: (u + 0.5)(u + 0.5) = -17.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
