Mark,

You might find my 'mpl' libraries interesting:

     http://github.com/dharmatech/mpl/blob/master/mpl.org

Solving equations and factoring polynomials are covered in volume 2 of 
the texts I mention there. Should you decide to implement those 
algorithms, the 'mpl' libraries could serve as a foundation for you to 
get started.
