Thank you for introducing the "depressed cubic" method.  It really helps me a lot in solving cubic equation.  

However, in your method there can only be a solution in the step of taking p = 3st, q = s3 + t3, if there is really 3 real roots, can this method also solve for all of them?  If yes, how should it be done?  If not, what will be the root solved out?  The largest or the smallest?

I would be thankful if you can answer my problem.  Sorry for my bad grammar.
