3 + w + 3w2 = 0

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

Divide each side by '3'.
1 + 0.3333333333w + w2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 0.3333333333w + -1 + w2 = 0 + -1

Reorder the terms:
1 + -1 + 0.3333333333w + w2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 0.3333333333w + w2 = 0 + -1
0.3333333333w + w2 = 0 + -1

Combine like terms: 0 + -1 = -1
0.3333333333w + w2 = -1

The w term is w.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.3333333333w + 0.25 + w2 = -1 + 0.25

Reorder the terms:
0.25 + 0.3333333333w + w2 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + 0.3333333333w + w2 = -0.75

Factor a perfect square on the left side:
(w + 0.5)(w + 0.5) = -0.75

Can't calculate square root of the right side.
