Multiplying, Dividing and Rationalizing Square Roots

In this video, we’ll guide you through the process of multiplying, dividing, and rationalizing square root expressions, important concepts in Algebra 1. We’ll start by covering the rules for multiplying and dividing square roots, and then move on to rationalizing denominators. Each time we check to make sure our answer is in simplest radical form! We discuss the motivation for rationalizing denominators when trying to identify like terms to add or subtract square root expressions. With clear examples and step-by-step explanations, you’ll gain the skills needed to confidently work with square root expressions in various contexts. Perfect for students looking to strengthen their understanding of these key operations!
