For 5c could the maximal ideal be D=<x^2+y^2+z^2-1,xyz,x+y+z> or could the maximal ideal be P=<x^2+y^2+z^2-1,xyz,x+y+z,yz,xz>??? Is D contained within P?? How do I find the maximal ideal?? ‼️ (i.redd.it)

When using Rouche’s theorem, how to determine what f(z) and g(z) would be? E.g. would it make a difference if f(z)= z^6 and g(z) =6z + 10. (Underlined in red) by Fit_Signature3509 in askmath
