Factoring means to rewrite an expression as a product. In this lesson we are going to take a look at the greatest common factor and the technique of factor by grouping. First we will learn how to recognize the greatest common factor for a list of different terms and how we can actually factor out that greatest common factor when you have a polynomial. The greatest common factor is the greatest quantity that would evenly divide into all of the terms. This could be made up of numbers and variables. A good way of breaking down a large polynomial is factor by grouping.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
