Use Solve...
In[63]:=
N[Solve[(3 + 4*I)*x^3 + (4 - 2*I)*x^2 - I*x + 3 - I == 0, x]]
Out[63]=
{{x -> 0.03223195055443208 - 0.5929499450475026*I},
{x -> 0.6136331348505185 + 0.8350210304311797*I},
{x -> -0.8058650854049505 + 0.6379289146163232*I}}
Omit the N if you want the (rather lengthy) analytical expressions.
