Factor2[poly]
factors a polynomial in a standard way.
Factor2
works sometimes better than Factor on polynomials involving rationals with sums in the denominator.
Factor2
uses Factor
internally and is in general slower than Factor
. There are four possible settings of the option Method
(0
,1
,2
,3
). In general, Factor
will work faster than Factor2
.
