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

Divide each side by '3'.
2 + -0.3333333333y + y2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + -0.3333333333y + -2 + y2 = 0 + -2

Reorder the terms:
2 + -2 + -0.3333333333y + y2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -0.3333333333y + y2 = 0 + -2
-0.3333333333y + y2 = 0 + -2

Combine like terms: 0 + -2 = -2
-0.3333333333y + y2 = -2

The y term is -0.3333333333y.  Take half its coefficient (-0.1666666667).
Square it (0.02777777779) and add it to both sides.

Add '0.02777777779' to each side of the equation.
-0.3333333333y + 0.02777777779 + y2 = -2 + 0.02777777779

Reorder the terms:
0.02777777779 + -0.3333333333y + y2 = -2 + 0.02777777779

Combine like terms: -2 + 0.02777777779 = -1.97222222221
0.02777777779 + -0.3333333333y + y2 = -1.97222222221

Factor a perfect square on the left side:
(y + -0.1666666667)(y + -0.1666666667) = -1.97222222221

Can't calculate square root of the right side.
