Solving for variable 'w'.

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

Divide each side by '16'.
0.0625 + -1.125w + w2 = 0

Move the constant term to the right:

Add '-0.0625' to each side of the equation.
0.0625 + -1.125w + -0.0625 + w2 = 0 + -0.0625

Reorder the terms:
0.0625 + -0.0625 + -1.125w + w2 = 0 + -0.0625

Combine like terms: 0.0625 + -0.0625 = 0.0000
0.0000 + -1.125w + w2 = 0 + -0.0625
-1.125w + w2 = 0 + -0.0625

Combine like terms: 0 + -0.0625 = -0.0625
-1.125w + w2 = -0.0625

The w term is -1.125w.  Take half its coefficient (-0.5625).
Square it (0.31640625) and add it to both sides.

Add '0.31640625' to each side of the equation.
-1.125w + 0.31640625 + w2 = -0.0625 + 0.31640625

Reorder the terms:
0.31640625 + -1.125w + w2 = -0.0625 + 0.31640625

Combine like terms: -0.0625 + 0.31640625 = 0.25390625
0.31640625 + -1.125w + w2 = 0.25390625
