I am sure my calculator can do this, i just cant figure out how. For example, is there a way i can have the calculator work out [(6-x^2)^2-(6-4x+x^2)^2], to get the answer?
There is an add-on application you can buy for $50.
Zoom Math 200 - Algebra 1 Program for TI-83 Plus and TI-84 Plus Graphing Calculators
It looks like it at least lets you expand using FOIL; not sure about what else it can do.
Maybe it can help though.
