5.1.32 factorize

Syntax:
factorize ( poly_expression )
factorize ( poly_expression, 0 )
factorize ( poly_expression, 2 )
Type:
list of ideal and intvec
Syntax:
factorize ( poly_expression, 1 )
Type:
ideal
Purpose:
computes the irreducible factors (as an ideal) of the polynomial together with or without the multiplicities (as an intvec) depending on the second argument:
 
    0: returns factors and multiplicities, first factor is a constant.
       May also be written with only one argument.
    1: returns non-constant factors (no multiplicities).
    2: returns non-constant factors and multiplicities.
Note:
Not implemented for the coefficient fields real and finite fields of type (p^n,a).
Example:
 
See absFactorize; poly.
