Hi,

I'm writing some problems in which I'd

like some manipulation and simplification

of polynomials to be done automatically

(produce a polynomial in standard form

with some given roots and multiplicities,

or the sum, difference or product of such,

etc.).

Two sources of existing code for this are

macros/PGpolynomialmacros.pl (which

contains some obvious and easy to fix

bugs) and lib/Polynomial.pm (which I

seem to have to load forcibly).

Is there an existing recommended way

to accomplish what I want to do?

Thanks for any input.
