Factor Polynomials

Program updates the TI-89 Polyfact() which factors polynomial functions. The method of data input has been changed, making entry more user friendly and also making it easier to notice and correct errors. Choose rational factors only, include irrational factors, or include complex factors to factor completely. Or do them in sequence to see the progression. Toggle the displayed factors between Auto and Approx mode. The program uses factor() and cfactor(), but the input is easier, coefficients only. The factored forms are copied to the home screen so they can be more easily used in further calculations.
