Simplifying Radicals

In this lesson I will teach you how to simplify radicals.  A radical is a “square root” expression.  Just like we simplify a fraction by reducing it we will be writing radical expressions in there simplest form.  One of the most common mistakes students make in this topic is they figure they can always use their calculator to find the square root of any number- so they don’t really focus on mastering the skill of simplifying radicals.  However as you will see the concepts we will learn in the lesson apply to more than square roots of numbers they also apply to square roots containing variables.  As such a calculator will not help you much when you’re looking to simply a radical with variables inside.  This is a very important topic and lesson so take good notes and practice as much as you can.
