A quadratic trinomial is a polynomial with three unlike terms and degree two. For example; X² + 3x + 3 is a quadratic trinomial. First term is X² which is called the quadratic term, second term is +3x which is called the linear term and third term is 3 which is called the constant term.
Factoring a quadratic trinomial is the reverse of "FOIL" (I had a post on FOIL on how to multiply two binomials). In other words, once a trinomial is factorize we get two binomials as the factors of the trinomial.
I have explained below the very easy process to factorize a standard trinomial;
This is the first lesson on a series of factorizing trinomials lessons.
