I am new here and hope this is the right place for this question. I recently purchased the above mentioned calculator and would like to know if anyone knows of a program so I can do synthetic divsion to find all zeros of a polynomial.

Thank you

I am not aware how you can perform a synthetic division on the TI84P. Rather, there another method can be used, which basically would give you the results of a synthetic division.

Try

factor (expression) . One of the factors will be equal to your divisor. However, I suppose that if there are remainders, you will not see your expression among the factors obtained.

But I hope that part helped :) - Oct 23rd 2008, 03:48 PMAQA
Any help is better than none. Thank you.

I found a nice little application that can do synthetic division, but it is for TI 89 Titanium. Try to find a hack that can make TI89 apps work on TI84P.

Link to TI synthetic division app:

Algebra Resources

Section 2.5 discusses the function in question:

2.5*syndiv( {aN, a(N-1), ..., a2, a1, a0}, {r} )*I have a Ti89 Titanium, but it is still a hugely limited calculator. You cannot plot a graph in terms in x. There is only the Y= editor. Microsoft Math 3.0 has this functionality, which makes graphing of non-functions, for example, circles and ellipse an easy feat.

I hope TI builds a better and more versatile calculator.

If you want, you can download a TI89 Titanium emulator.

All you need is:

1) TiEmu (ticalc/google)

2) GTK2 runtime (sourceforge/google)

3) A Ti89 Titanium OS (download from TI)

If you are having problems with setting the emulator, I shall help you.

Good luck.
