Factoring Trinomials with U Substitution

This video tutorial covers the process of factoring trinomials using U substitution. It begins with an introduction to the concept and then provides two detailed examples. The first example demonstrates factoring X to the fourth plus five X squared plus six, while the second example focuses on factoring X to the sixth. The video concludes with a summary and additional resources for further learning.
