How to Add and Subtract Radical Expressions (Square Roots)\Algebra [Worked Example📝]

Be sure to subscribe to the channel!

In this video I show you everything you need to know about how to Add and Subtract Radical Expressions involving Square Roots. Whether you're in Algebra, Algebra 2, Geometry or Trig, this method WORKS. I show you the exact steps and strategy you need to know to Add and Subtract Square Root Expressions. The two keys are to make sure each radical is fully simplified first and then identify the like terms. Over the years I've seen students make the same two mistakes over and over again. They don't fully simplify the radical and they don't know how to identify like terms involving square roots. I show you how to NOT make these same mistakes. These techniques I show you in this worked example will ensure that you get the right answer. I also point out common mistakes, misconceptions, and errors that I've seen students make in the classroom and show you how to avoid them.

Hope this helps you.
