Solving for variable 'w'.

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

Divide each side by '2'.
2.5 + -5w + w2 = 0

Move the constant term to the right:

Add '-2.5' to each side of the equation.
2.5 + -5w + -2.5 + w2 = 0 + -2.5

Reorder the terms:
2.5 + -2.5 + -5w + w2 = 0 + -2.5

Combine like terms: 2.5 + -2.5 = 0.0
0.0 + -5w + w2 = 0 + -2.5
-5w + w2 = 0 + -2.5

Combine like terms: 0 + -2.5 = -2.5
-5w + w2 = -2.5

The w term is -5w.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5w + 6.25 + w2 = -2.5 + 6.25

Reorder the terms:
6.25 + -5w + w2 = -2.5 + 6.25

Combine like terms: -2.5 + 6.25 = 3.75
6.25 + -5w + w2 = 3.75

Factor a perfect square on the left side:
(w + -2.5)(w + -2.5) = 3.75

Calculate the square root of the right side: 1.936491673

Break this problem into two subproblems by setting 
(w + -2.5) equal to 1.936491673 and -1.936491673.
