You should be a little wary of tanking through your homework with programs, especially if your teacher cares enough to dock you points for missing work.
That said, Zoom Math is pretty much the only thing on TI that's gonna do it for you (though
AutoCalc might be worth a look).
If the problems that you're having trouble with are all pretty much of the same type, you might consider writing a program yourself: in my experience, that's an excellent way of figuring out how to do the problem on your own, anyway. (In fact, I think I had a BASIC routine around for polynomial division ages ago...)
