Factoring Trinomials by Grouping (Example 1)

This factoring by grouping tutorial video explains an example of how to factor a trinomial using the grouping method. We show you how to split the middle term into two separate terms, so this factoring by grouping 3 terms problem is actually transformed into a factoring by grouping 4 terms problem. Once we regroup the middle term, we then complete this factor trinomials example using the method of grouping the 4 terms. Factoring trinomials by grouping is a common method and many of the other factoring methods are based on this method.
