Solving for variable 'v'.

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

Divide each side by '2'.
8.5 + -6.5v + v2 = 0

Move the constant term to the right:

Add '-8.5' to each side of the equation.
8.5 + -6.5v + -8.5 + v2 = 0 + -8.5

Reorder the terms:
8.5 + -8.5 + -6.5v + v2 = 0 + -8.5

Combine like terms: 8.5 + -8.5 = 0.0
0.0 + -6.5v + v2 = 0 + -8.5
-6.5v + v2 = 0 + -8.5

Combine like terms: 0 + -8.5 = -8.5
-6.5v + v2 = -8.5

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 = -8.5 + 10.5625

Reorder the terms:
10.5625 + -6.5v + v2 = -8.5 + 10.5625

Combine like terms: -8.5 + 10.5625 = 2.0625
10.5625 + -6.5v + v2 = 2.0625

Factor a perfect square on the left side:
(v + -3.25)(v + -3.25) = 2.0625

Calculate the square root of the right side: 1.436140662

Break this problem into two subproblems by setting 
(v + -3.25) equal to 1.436140662 and -1.436140662.

Subproblem 1

v + -3.25 = 1.436140662 Simplifying v + -3.25 = 1.436140662 Reorder the terms: -3.25 + v = 1.436140662 Solving -3.25 + v = 1.436140662 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '3.25' to each side of the equation. -3.25 + 3.25 + v = 1.436140662 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + v = 1.436140662 + 3.25 v = 1.436140662 + 3.25 Combine like terms: 1.436140662 + 3.25 = 4.686140662 v = 4.686140662 Simplifying v = 4.686140662

Subproblem 2

v + -3.25 = -1.436140662 Simplifying v + -3.25 = -1.436140662 Reorder the terms: -3.25 + v = -1.436140662 Solving -3.25 + v = -1.436140662 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '3.25' to each side of the equation. -3.25 + 3.25 + v = -1.436140662 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + v = -1.436140662 + 3.25 v = -1.436140662 + 3.25 Combine like terms: -1.436140662 + 3.25 = 1.813859338 v = 1.813859338 Simplifying v = 1.813859338
