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

Divide each side by '2'.
2.5 + -6.5v + v2 = 0

Move the constant term to the right:

Add '-2.5' to each side of the equation.
2.5 + -6.5v + -2.5 + v2 = 0 + -2.5

Reorder the terms:
2.5 + -2.5 + -6.5v + v2 = 0 + -2.5

Combine like terms: 2.5 + -2.5 = 0.0
0.0 + -6.5v + v2 = 0 + -2.5
-6.5v + v2 = 0 + -2.5

Combine like terms: 0 + -2.5 = -2.5
-6.5v + v2 = -2.5

The v term is -6.5v.  Take half its coefficient (-3.25).
Square it (10.5625) and add it to both sides.

Add '10.5625' to each side of the equation.
-6.5v + 10.5625 + v2 = -2.5 + 10.5625

Reorder the terms:
10.5625 + -6.5v + v2 = -2.5 + 10.5625

Combine like terms: -2.5 + 10.5625 = 8.0625
10.5625 + -6.5v + v2 = 8.0625

Factor a perfect square on the left side:
(v + -3.25)(v + -3.25) = 8.0625

Calculate the square root of the right side: 2.839454173
