Simplifying Radicals with Coefficients

The video tutorial covers the process of simplifying radicals, starting with an introduction to the concept and moving through several examples. The teacher explains how to factor numbers using prime factorization, identify pairs of factors, and simplify the expression by moving pairs outside the radical. Each example demonstrates these steps in detail, ensuring students understand the process. The video concludes with a summary of the steps involved in simplifying radicals.
