Simplifying u2 + -22u + 180 = 0 Reorder the terms: 180 + -22u + u2 = 0 Solving 180 + -22u + u2 = 0 Solving for variable 'u'. Begin completing the square. Move the constant term to the right: Add '-180' to each side of the equation. 180 + -22u + -180 + u2 = 0 + -180 Reorder the terms: 180 + -180 + -22u + u2 = 0 + -180 Combine like terms: 180 + -180 = 0 0 + -22u + u2 = 0 + -180 -22u + u2 = 0 + -180 Combine like terms: 0 + -180 = -180 -22u + u2 = -180 The u term is -22u. Take half its coefficient (-11). Square it (121) and add it to both sides. Add '121' to each side of the equation. -22u + 121 + u2 = -180 + 121 Reorder the terms: 121 + -22u + u2 = -180 + 121 Combine like terms: -180 + 121 = -59 121 + -22u + u2 = -59 Factor a perfect square on the left side: (u + -11)(u + -11) = -59 Can't calculate square root of the right side. The solution to this equation could not be determined.
