No it wasn't Maple. I'm familiar with Maple. I found it by following ads in MacWorld magazine back in the day. It should be identifiable by checking issues between December 1984 and May 1987.
Thank you for the link. I'm pretty sure I found it in the Internet Archive's issues of MacWorld from back in the day.
On page 9 (10 in the archive) of the April 1988 issue there is an advert for Eureka: The Solver by Borland International (Of course! They had such excellent software for years.)
There is a writeup about it on pages 191-192 (pages 192-193 in the archive).
One of the tools available is a polynomial finder. That is the tool that I used.
I will look around to see whether I still have the disk.
I also found my favorite, and first computer game since it was my first computer.
Silicon Beach Software put out a game called Airborne! in 1984. I got the Mac in January 1985 and bought that game with it. Fun stuff!
