Since I jumped straight to member, I don't want this program to go to waste.
This is a polynomial program that is very small and fast. (About 330 bytes.)
You enter in an expression involving X and it will put it in polynomial form.
For example, enter in
(X-1)2-1
and it will show
x2-2x
Plus, it uses no strings!
