I would like to use my Casio fx-9860gii in pre-calc, but my teacher suggests the TI-89. One of the things she told me to do was see if I could expand on my calculator. For example, plugging in (x-5)(2x-1)(3x+2) in the calculator and having it expanded to 6x^3-29x^2-7x+10. Is this possible on my calculator?

The fx-9860GII doesn't have a Computer Algebra System built in.

There is a couple of add-in application such as symbolix which easily handles an expansion like that, try symbolix:

Believe you teacher and buy Ti 89. I've done a mistake and bought discount Casio 9860G and I regret it now. With Casio you cannot develop your own subroutines as it contains only global variable array - no stack, no procedure params, no local variables, multicharacter variable id's. Applications available are only stupid games not really usefull engineering application because of previous limitation. This calculator may be useful only for primary or secondary school, but definitelly not for a University...
