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

Divide each side by '4'.
6 + -7.75v + v2 = 0

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -7.75v + -6 + v2 = 0 + -6

Reorder the terms:
6 + -6 + -7.75v + v2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -7.75v + v2 = 0 + -6
-7.75v + v2 = 0 + -6

Combine like terms: 0 + -6 = -6
-7.75v + v2 = -6

The v term is -7.75v.  Take half its coefficient (-3.875).
Square it (15.015625) and add it to both sides.

Add '15.015625' to each side of the equation.
-7.75v + 15.015625 + v2 = -6 + 15.015625

Reorder the terms:
15.015625 + -7.75v + v2 = -6 + 15.015625

Combine like terms: -6 + 15.015625 = 9.015625
15.015625 + -7.75v + v2 = 9.015625

Factor a perfect square on the left side:
(v + -3.875)(v + -3.875) = 9.015625
