This is an equation:T*s^3+s^2+K=0,where T>0,K>0, s is complex variable. I have known that one of its roots has real part, and this real part is independent of T and K. I don't know how can I use maple to illustrate this conclusion, can you give me some advices? I try to use solve command, but the result is very chaotic.

Thank you in advance.
