Solving for variable 'u'.

Begin completing the square.

Move the constant term to the right:

Add '-27' to each side of the equation.
27 + -26u + -27 + u2 = 0 + -27

Reorder the terms:
27 + -27 + -26u + u2 = 0 + -27

Combine like terms: 27 + -27 = 0
0 + -26u + u2 = 0 + -27
-26u + u2 = 0 + -27

Combine like terms: 0 + -27 = -27
-26u + u2 = -27

The u term is -26u.  Take half its coefficient (-13).
Square it (169) and add it to both sides.

Add '169' to each side of the equation.
-26u + 169 + u2 = -27 + 169

Reorder the terms:
169 + -26u + u2 = -27 + 169

Combine like terms: -27 + 169 = 142
169 + -26u + u2 = 142

Factor a perfect square on the left side:
(u + -13)(u + -13) = 142
