Lesson Summary:
In this lesson, Professor Perez from Saddleback College teaches us how to factor polynomials by grouping. Factoring by grouping requires forming two groups and taking out the greatest common factor of each group. Charlie, the professor's assistant, helps by identifying the greatest common factor for each group and even encourages cheating by using the fact that the same binomial will show up in each group. Through this process, the original polynomial is broken down into simpler expressions that can be more easily solved.
