6 + -38v + 25v2 = 0

Solving for variable 'v'.

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

Divide each side by '25'.
0.24 + -1.52v + v2 = 0

Move the constant term to the right:

Add '-0.24' to each side of the equation.
0.24 + -1.52v + -0.24 + v2 = 0 + -0.24

Reorder the terms:
0.24 + -0.24 + -1.52v + v2 = 0 + -0.24

Combine like terms: 0.24 + -0.24 = 0.00
0.00 + -1.52v + v2 = 0 + -0.24
-1.52v + v2 = 0 + -0.24

Combine like terms: 0 + -0.24 = -0.24
-1.52v + v2 = -0.24

The v term is -1.52v.  Take half its coefficient (-0.76).
Square it (0.5776) and add it to both sides.

Add '0.5776' to each side of the equation.
-1.52v + 0.5776 + v2 = -0.24 + 0.5776

Reorder the terms:
0.5776 + -1.52v + v2 = -0.24 + 0.5776

Combine like terms: -0.24 + 0.5776 = 0.3376
0.5776 + -1.52v + v2 = 0.3376

Factor a perfect square on the left side:
(v + -0.76)(v + -0.76) = 0.3376

Calculate the square root of the right side: 0.581033562
