# irreducibility of a polynomial

If f $f(x)$ is a polynomial, i know that the command $f.factor()$ gives the factorization of f. But I am interested in knowing whether the polynomial is irreducible or not, not its factors. Is there any command for that ?

To display inline code, surround it within backticks

`...`

. This way you could get`f.factor()`

instead of $f.factor()$.thanks @slelievre
