I have the next function: z^32xz+y=0 and I want to find taylor expansion of z(x,y) at the point (1,1,1), obviously I need to define F(x,y,z) as above and use the implicit function theorem to calculate the derivatives of z(x,y), but I want mathematica to compute this to me.
I tried the Series command but I don't know how to use such that it will use the implicit function theorem in the computation. Any help? Thanks, I tried looking at the documentation of Mathematica but didn't find anything about taylor expansion of implicit functions.

I think you're going to have to write a routine for that. I can show you how to get the first partial with respect to x. Do the same for y, then iterate:
