gives a list in which the first element is the overall numerical factor in poly, and the second element is the polynomial with the overall factor removed.


gives a list of factors of poly. The first element in the list is the overall numerical factor. The second element is a factor that does not depend on any of the xi. Subsequent elements are factors which depend on progressively more of the xi.
