Simplifying u2 + 20u + 101 = 0 Reorder the terms: 101 + 20u + u2 = 0 Solving 101 + 20u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-101' to each side of the equation. 101 + 20u + -101 + u2 = 0 + -101 Reorder the terms: 101 + -101 + 20u + u2 = 0 + -101 Combine like terms: 101 + -101 = 0 0 + 20u + u2 = 0 + -101 20u + u2 = 0 + -101 Combine like terms: 0 + -101 = -101 20u + u2 = -101 The u term is 20u. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20u + 100 + u2 = -101 + 100 Reorder the terms: 100 + 20u + u2 = -101 + 100 Combine like terms: -101 + 100 = -1 100 + 20u + u2 = -1 Factor a perfect square on the left side: (u + 10)(u + 10) = -1 Can't calculate square root of the right side. The solution to this equation could not be determined.
