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

Divide each side by '625'.
0.0144 + -0.048v + v2 = 0

Move the constant term to the right:

Add '-0.0144' to each side of the equation.
0.0144 + -0.048v + -0.0144 + v2 = 0 + -0.0144

Reorder the terms:
0.0144 + -0.0144 + -0.048v + v2 = 0 + -0.0144

Combine like terms: 0.0144 + -0.0144 = 0.0000
0.0000 + -0.048v + v2 = 0 + -0.0144
-0.048v + v2 = 0 + -0.0144

Combine like terms: 0 + -0.0144 = -0.0144
-0.048v + v2 = -0.0144

The v term is -0.048v.  Take half its coefficient (-0.024).
Square it (0.000576) and add it to both sides.

Add '0.000576' to each side of the equation.
-0.048v + 0.000576 + v2 = -0.0144 + 0.000576

Reorder the terms:
0.000576 + -0.048v + v2 = -0.0144 + 0.000576

Combine like terms: -0.0144 + 0.000576 = -0.013824
0.000576 + -0.048v + v2 = -0.013824

Factor a perfect square on the left side:
(v + -0.024)(v + -0.024) = -0.013824

Can't calculate square root of the right side.
