Solving for variable 'w'.

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

Divide each side by '2'.
-182 + 2.5w + w2 = 0

Move the constant term to the right:

Add '182' to each side of the equation.
-182 + 2.5w + 182 + w2 = 0 + 182

Reorder the terms:
-182 + 182 + 2.5w + w2 = 0 + 182

Combine like terms: -182 + 182 = 0
0 + 2.5w + w2 = 0 + 182
2.5w + w2 = 0 + 182

Combine like terms: 0 + 182 = 182
2.5w + w2 = 182

The w term is 2.5w.  Take half its coefficient (1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
2.5w + 1.5625 + w2 = 182 + 1.5625

Reorder the terms:
1.5625 + 2.5w + w2 = 182 + 1.5625

Combine like terms: 182 + 1.5625 = 183.5625
1.5625 + 2.5w + w2 = 183.5625

Factor a perfect square on the left side:
(w + 1.25)(w + 1.25) = 183.5625
