Computer algebra packages typically factor using [Gröbner basis](http://en.wikipedia.org/wiki/Gr%C3%B6bner_basis) algorithms, [Berlekamp's method](http://en.wikipedia.org/wiki/Berlekamp%27s_algorithm), [Niederreiter's method](http://www.math.uzh.ch/?file&amp;key1=9314), [Zassenhaus' algorithm](http://en.wikipedia.org/wiki/Cantor%E2%80%93Zassenhaus_algorithm), [LLL lattice reduction methods](http://www.math.fsu.edu/~hoeij/papers/issac10/A.pdf), or [Gao's diffy-que path](http://www.sciencedirect.com/science/article/pii/S0304397510006869), typically using a number of alterations specifically for improvements in implementation speed or simplicity.

If you are looking for the methods taught before college - basic high school methods - you won't get a very complete implementation or find factors beyond quadratic.  A textbook would be precisely the best place to look, since that would be complete in that fashion.
