Some help to finish this...

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Define ext()=
Prgm
:Local fx,fy,fxx,fyy,f1,po,x,y
:Disp "Finding local max, min, and saddle points"
:Request "Type function",f1
:fx:=d/dx(f1,x)
:fy:=d/dy(f1,y)

Now how can I do

solve(system(f1=0,f2=0),{x,y}) and put in a two distinct variables
Would be with a matrices or a list?
And how to do?
Im not finish but I am not knowing where to go from here

TY for any help…
