Solving for variable 'u'.

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
37 + 5.5u + u2 = 0

Move the constant term to the right:

Add '-37' to each side of the equation.
37 + 5.5u + -37 + u2 = 0 + -37

Reorder the terms:
37 + -37 + 5.5u + u2 = 0 + -37

Combine like terms: 37 + -37 = 0
0 + 5.5u + u2 = 0 + -37
5.5u + u2 = 0 + -37

Combine like terms: 0 + -37 = -37
5.5u + u2 = -37

The u term is 5.5u.  Take half its coefficient (2.75).
Square it (7.5625) and add it to both sides.

Add '7.5625' to each side of the equation.
5.5u + 7.5625 + u2 = -37 + 7.5625

Reorder the terms:
7.5625 + 5.5u + u2 = -37 + 7.5625

Combine like terms: -37 + 7.5625 = -29.4375
7.5625 + 5.5u + u2 = -29.4375

Factor a perfect square on the left side:
(u + 2.75)(u + 2.75) = -29.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
