Solving for variable 'v'.

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

Divide each side by '3'.
15.33333333 + 7v + v2 = 0

Move the constant term to the right:

Add '-15.33333333' to each side of the equation.
15.33333333 + 7v + -15.33333333 + v2 = 0 + -15.33333333

Reorder the terms:
15.33333333 + -15.33333333 + 7v + v2 = 0 + -15.33333333

Combine like terms: 15.33333333 + -15.33333333 = 0.00000000
0.00000000 + 7v + v2 = 0 + -15.33333333
7v + v2 = 0 + -15.33333333

Combine like terms: 0 + -15.33333333 = -15.33333333
7v + v2 = -15.33333333

The v term is 7v.  Take half its coefficient (3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
7v + 12.25 + v2 = -15.33333333 + 12.25

Reorder the terms:
12.25 + 7v + v2 = -15.33333333 + 12.25

Combine like terms: -15.33333333 + 12.25 = -3.08333333
12.25 + 7v + v2 = -3.08333333

Factor a perfect square on the left side:
(v + 3.5)(v + 3.5) = -3.08333333

Can't calculate square root of the right side.

The solution to this equation could not be determined.
