Peter Mitsis 83d00839ed fvi: Refactor solution to quadratic formula ...

The classic solution to the quadratic equation ...
     a*x*x + b*x + c = 0
is ...
         -b +- sqrt(b*b - 4*ac)
     x = ----------------------
                 2*a

This can be optimized by substituting b = 2*B.
         -2*B +- sqrt((2*B)*(2*B) - 4*a*c)
     x = ---------------------------------
                       2*a

This expands to ...
         -2*B +- sqrt(4*B*B - 4*a*c)
     x = ---------------------------
                    2*a

And simplifies to ...
         -2*B +- 2*sqrt(B*B - 4*a*c)
     x = ---------------------------
                    2*a

         -B +- sqrt(B*B - a*c)
     x = ---------------------
                  a
