Advanced Factoring - YourTeacher.com - 1000+ Online Math Lessons

For a complete lesson on advanced factoring, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that the last step in some factoring problems is to factor the difference of two squares. For example, the trinomial x^4 + 2x^2 -- 3 factors as (x^2 + 3)(x^2 -- 1), and as a last step, since the binomial (x^2 -- 1) represents the difference of two squares, it factors as (x + 1)(x -- 1), so the final answer is (x^2 + 3)(x + 1)(x -- 1).

Factoring is a pain in the ass for me, so this is a real question, not me being sarcastic.

Why wouldn't you factor the other (x^+1)?

@ThomasBHofSoCal algebra is used in science for chimical&phisycal equation

[megallgurl]

why does the x^2 +1 get factored out only once why does the other one right after the x^2 stay the same?

[megallgurl]

where does the -1 come from
