This topic is in the 'Polynomials and Factoring' section. When we learn about numbers, we find multiplying numbers together gives us new numbers. If we multiply integers together we get newer bigger integers. And if we take a big integer, we can figure out what other integers we need to multiply to get that bigger integer. That's the basic idea behind factoring, and amazingly, every single number can be factored uniquely into smaller primes. Now Algebra is all about taking ideas that we come across with numbers and generalizing those ideas, and that's where polynomials come from. Instead of multiplying integers together to get bigger integers, we can multiply variable expressions together to get more complex variable expressions that we call polynomials. We can also go backwards, and look at what variable expressions we need to multiply together to get a polynomial. That's called polynomial factoring, and it's very close to the idea of doing prime factorization for numbers. The tutorials in this section will help you see these connections and give you some examples to learn from, so check them out!
