Simplifying u2 + -221u + 16900 = 0 Reorder the terms: 16900 + -221u + u2 = 0 Solving 16900 + -221u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-16900' to each side of the equation. 16900 + -221u + -16900 + u2 = 0 + -16900 Reorder the terms: 16900 + -16900 + -221u + u2 = 0 + -16900 Combine like terms: 16900 + -16900 = 0 0 + -221u + u2 = 0 + -16900 -221u + u2 = 0 + -16900 Combine like terms: 0 + -16900 = -16900 -221u + u2 = -16900 The u term is -221u. Take half its coefficient (-110.5). Square it (12210.25) and add it to both sides. Add '12210.25' to each side of the equation. -221u + 12210.25 + u2 = -16900 + 12210.25 Reorder the terms: 12210.25 + -221u + u2 = -16900 + 12210.25 Combine like terms: -16900 + 12210.25 = -4689.75 12210.25 + -221u + u2 = -4689.75 Factor a perfect square on the left side: (u + -110.5)(u + -110.5) = -4689.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
