Factorization
To express a polynomial in fully factored form, use the factor command.
>
The factor command factors the polynomial over the ring implied by the
coefficients, for example, integers. You can specify an algebraic number
field over which to factor the polynomial. For more information, refer to the
?factor help page. (The ifactor command factors an integer. For more in-
formation, see Integer Operations (page 71).)
