Solving for variable 'v'.

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

Divide each side by '4'.
7.25 + -7v + v2 = 0

Move the constant term to the right:

Add '-7.25' to each side of the equation.
7.25 + -7v + -7.25 + v2 = 0 + -7.25

Reorder the terms:
7.25 + -7.25 + -7v + v2 = 0 + -7.25

Combine like terms: 7.25 + -7.25 = 0.00
0.00 + -7v + v2 = 0 + -7.25
-7v + v2 = 0 + -7.25

Combine like terms: 0 + -7.25 = -7.25
-7v + v2 = -7.25

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 = -7.25 + 12.25

Reorder the terms:
12.25 + -7v + v2 = -7.25 + 12.25

Combine like terms: -7.25 + 12.25 = 5
12.25 + -7v + v2 = 5

Factor a perfect square on the left side:
(v + -3.5)(v + -3.5) = 5

Calculate the square root of the right side: 2.236067978
