I don't know for which values you tested your code, but if the
discriminent (term which you apply sqrt to) equals 0, your equation
only has *one* solution. That's why you get two identical values.
Btw: You should check for a negative discriminent (that happens if
your equation isn't solvable at all)

Cheers,
