Lesson Summary:
In this lesson, a new method for factoring non-basic trinomials is introduced. The SEMM and product method is used, but it's not explained why it works. The key is to take the first coefficient and write it in three places, and then use the product and sum to find the missing numbers. Once the trinomial is factored, it's important to check the answer using the FOIL method. It's a nifty method that can be used if the traditional methods aren't working.
