    TI-84 plus silver edition

    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

    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.
