Solving for variable 'u'.

Begin completing the square.

Move the constant term to the right:

Add '-11' to each side of the equation.
11 + -6u + -11 + u2 = 0 + -11

Reorder the terms:
11 + -11 + -6u + u2 = 0 + -11

Combine like terms: 11 + -11 = 0
0 + -6u + u2 = 0 + -11
-6u + u2 = 0 + -11

Combine like terms: 0 + -11 = -11
-6u + u2 = -11

The u term is -6u.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6u + 9 + u2 = -11 + 9
