Factoring by Grouping
Learning Objective
I can factor polynomials with four terms by grouping.
Key Concepts
When factoring a polynomial with four terms, you can use the factor by grouping method.
When grouping, identify the common factor within each group and factor it out.
After factoring out the common factors from each group, factor out the common binomial to arrive at the final factored form.
