First, we break the trinomial up into two binomials that are multiplied together. We then write down the terms that multiply together to give us the first term of the trinomial, followed by the middle term and last term. In the process of factoring trinomials, we need to be careful to select the correct signs in the two binomials so that when we multiply them together, we get the correct sign of the middle term in the original trinomial. The steps in this tutorial are also very important as we study other topics in algebra such as factoring polynomials. When we factor a polynomial, many times we simply factor out a common term, after which we factor the remaining trinomial as usual. These steps are also used when factoring quadratic equations in high school and college algebra. Any topic in algebra can be mastered by working example problems step by step!
