Ferrari method for a complex 4th polynomio

Dear Community,

I have read on the internet I can use the Ferrari Method to solve a 4th-degree polynomial. Following this method, I have to obtain the real solution of the cubic equation before obtaining the roots of the 4th-degree equation. However, my cubic equation does not have a real solution because one of the coefficients is complex. So, I am quite stuck on this matter. Thanks so much in advance for your help.

Kind regards,

Estanis

Can you give me the original 4th degree polynomial that you're with?
