How to find the least common multiple of two trinomials

The video tutorial explains how to find the least common multiple (LCM) of polynomials by first factoring them into simpler terms. It emphasizes the importance of identifying common factors and constructing the LCM by including these common factors along with the unique factors from each polynomial. The process is demonstrated step-by-step, ensuring clarity in understanding the concept.
