Divide each side by '3'.
-0.6666666667 + v + v2 = 0

Move the constant term to the right:

Add '0.6666666667' to each side of the equation.
-0.6666666667 + v + 0.6666666667 + v2 = 0 + 0.6666666667

Reorder the terms:
-0.6666666667 + 0.6666666667 + v + v2 = 0 + 0.6666666667

Combine like terms: -0.6666666667 + 0.6666666667 = 0.0000000000
0.0000000000 + v + v2 = 0 + 0.6666666667
v + v2 = 0 + 0.6666666667

Combine like terms: 0 + 0.6666666667 = 0.6666666667
v + v2 = 0.6666666667

The v term is v.  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.
 + 0.25 + v2 = 0.6666666667 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + v2 = 0.6666666667 + 0.25
