Move the constant term to the right:

Add '-0.05833333333' to each side of the equation.
0.05833333333 + -0.025w + -0.05833333333 + w2 = 0 + -0.05833333333

Reorder the terms:
0.05833333333 + -0.05833333333 + -0.025w + w2 = 0 + -0.05833333333

Combine like terms: 0.05833333333 + -0.05833333333 = 0.00000000000
0.00000000000 + -0.025w + w2 = 0 + -0.05833333333
-0.025w + w2 = 0 + -0.05833333333

Combine like terms: 0 + -0.05833333333 = -0.05833333333
-0.025w + w2 = -0.05833333333

The w term is -0.025w.  Take half its coefficient (-0.0125).
Square it (0.00015625) and add it to both sides.
