FactorList

FactorList[poly] gives a list of the factors of a polynomial, together with their exponents.

The first element of the list is always the overall numerical factor. It is {1, 1} if there is no overall numerical factor.

Example: FactorList[3 (1+x)^2 (1-x)] .

FactorList[poly, Modulus->p] factors modulo a prime p.

FactorList[poly, GaussianIntegers->True] allows Gaussian integer coefficients.

FactorList[poly, Extension->, , ... ] allows coefficients that are arbitrary rational combinations of the .

See Section 3.3.4.
