Factoring by Grouping
Learning Objective
I can factor polynomials with four terms using the grouping method.
Key Concepts
The first step in factor by grouping is to factor out the greatest common factor.
When using factor by grouping with four terms, the first step is to divide the polynomial into halves and factor out the greatest common factor from each half.
If done correctly, the products will have a common polynomial factor that can be factored out to complete the problem.
