Jalen Deleon provides a tutorial on factoring binomials and trinomials. His method for factoring binomials is to find the greatest common factor. He also explains how to factor the difference of two perfect squares by breaking them down and putting the answer in parentheses. For trinomials, he uses the "diamond method" taught by his teacher Ms. Suhker. He provides examples of factoring 4j4-8 and D2-16 to demonstrate his methods.
