Solving for variable 'w'.

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

Divide each side by '4'.
-0.5 + 1.25w + w2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + 1.25w + 0.5 + w2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + 1.25w + w2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + 1.25w + w2 = 0 + 0.5
1.25w + w2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
1.25w + w2 = 0.5

The w term is 1.25w.  Take half its coefficient (0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
1.25w + 0.390625 + w2 = 0.5 + 0.390625

Reorder the terms:
0.390625 + 1.25w + w2 = 0.5 + 0.390625

Combine like terms: 0.5 + 0.390625 = 0.890625
0.390625 + 1.25w + w2 = 0.890625

Factor a perfect square on the left side:
(w + 0.625)(w + 0.625) = 0.890625

Calculate the square root of the right side: 0.943729304
