Which "school" did you have in mind? If you mean "high school", then the answer is that you won't find it. If you mean "college", then yes, you can find such algorithms in college level textbooks. Knuth's "The Art of Computer Programming" vol 2 contains an excellent introduction to algorithms that are certain to factor any polynomial.
The mathematics involved in general polynomial factoring algorithms is definitely college-level.
