Factoring out a Common Factor - Algebra I
In this video, you will learn how to factor out a common factor in a polynomial by using what is called factoring by grouping. When a polynomial has four terms, you can factor it by putting parenthesis around the first two terms and the last tow terms. Then you find the GCF or greatest common factor of each binomial. Then, divide the binomial by the GCF to factor. You should get the same binomial in the parenthesis after finding the GCF of each binomial and dividing. Next, just write the common binomial in one set of parenthesis and the two GCFs in the second set of parenthesis. The sign between the GCFs in the binomial are determined by the sign of the third term in the polynomial.
