Divide each side by '3'.
0.3333333333 + -6w + w2 = 0

Move the constant term to the right:

Add '-0.3333333333' to each side of the equation.
0.3333333333 + -6w + -0.3333333333 + w2 = 0 + -0.3333333333

Reorder the terms:
0.3333333333 + -0.3333333333 + -6w + w2 = 0 + -0.3333333333

Combine like terms: 0.3333333333 + -0.3333333333 = 0.0000000000
0.0000000000 + -6w + w2 = 0 + -0.3333333333
-6w + w2 = 0 + -0.3333333333

Combine like terms: 0 + -0.3333333333 = -0.3333333333
-6w + w2 = -0.3333333333

The w term is -6w.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6w + 9 + w2 = -0.3333333333 + 9

Reorder the terms:
9 + -6w + w2 = -0.3333333333 + 9

Combine like terms: -0.3333333333 + 9 = 8.6666666667
9 + -6w + w2 = 8.6666666667
