Solving for variable 'w'.

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

Divide each side by '2'.
-18.5 + 7.5w + w2 = 0

Move the constant term to the right:

Add '18.5' to each side of the equation.
-18.5 + 7.5w + 18.5 + w2 = 0 + 18.5

Reorder the terms:
-18.5 + 18.5 + 7.5w + w2 = 0 + 18.5

Combine like terms: -18.5 + 18.5 = 0.0
0.0 + 7.5w + w2 = 0 + 18.5
7.5w + w2 = 0 + 18.5

Combine like terms: 0 + 18.5 = 18.5
7.5w + w2 = 18.5

The w term is 7.5w.  Take half its coefficient (3.75).
Square it (14.0625) and add it to both sides.

Add '14.0625' to each side of the equation.
7.5w + 14.0625 + w2 = 18.5 + 14.0625

Reorder the terms:
14.0625 + 7.5w + w2 = 18.5 + 14.0625

Combine like terms: 18.5 + 14.0625 = 32.5625
14.0625 + 7.5w + w2 = 32.5625

Factor a perfect square on the left side:
(w + 3.75)(w + 3.75) = 32.5625
