Simplifying u2 + -3u + 200 = 0 Reorder the terms: 200 + -3u + u2 = 0 Solving 200 + -3u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-200' to each side of the equation. 200 + -3u + -200 + u2 = 0 + -200 Reorder the terms: 200 + -200 + -3u + u2 = 0 + -200 Combine like terms: 200 + -200 = 0 0 + -3u + u2 = 0 + -200 -3u + u2 = 0 + -200 Combine like terms: 0 + -200 = -200 -3u + u2 = -200 The u term is -3u. 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. -3u + 2.25 + u2 = -200 + 2.25 Reorder the terms: 2.25 + -3u + u2 = -200 + 2.25 Combine like terms: -200 + 2.25 = -197.75 2.25 + -3u + u2 = -197.75 Factor a perfect square on the left side: (u + -1.5)(u + -1.5) = -197.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
