Solving for variable 'v'.

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

Divide each side by '7'.
1.571428571 + 2v + v2 = 0

Move the constant term to the right:

Add '-1.571428571' to each side of the equation.
1.571428571 + 2v + -1.571428571 + v2 = 0 + -1.571428571

Reorder the terms:
1.571428571 + -1.571428571 + 2v + v2 = 0 + -1.571428571

Combine like terms: 1.571428571 + -1.571428571 = 0.000000000
0.000000000 + 2v + v2 = 0 + -1.571428571
2v + v2 = 0 + -1.571428571

Combine like terms: 0 + -1.571428571 = -1.571428571
2v + v2 = -1.571428571

The v term is 2v.  Take half its coefficient (1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
2v + 1 + v2 = -1.571428571 + 1

Reorder the terms:
1 + 2v + v2 = -1.571428571 + 1

Combine like terms: -1.571428571 + 1 = -0.571428571
1 + 2v + v2 = -0.571428571

Factor a perfect square on the left side:
(v + 1)(v + 1) = -0.571428571

Can't calculate square root of the right side.
