Video: Operations with Radical Expressions (Algebra 2)

Topic of this video:  Operations with Radicals

Unit: Radicals, Exponents, Complex Numbers, Factoring

Course: Algebra 2

Video Duration:  11 minutes and 21 seconds

This video:

• Explains examples of operations (adding, subtracting, multiplying and dividing) of radicals 
• Explains the concept of like radicals and why they can be combined and why unlike radicals cannot be combined
• Shows and explains an example of multiplying two binomials containing radicals
• Shows and explains an example of adding cube roots with variables
• Shows and explains an example of distributing expressions with polynomials and radicals

Hello!  I created this video for students to learn this topic independently.  This video is a tool you can use to teach, preview, reteach, or just have as an additional resource.   The video uses student-friendly language and explains topics as simply as possible.  If you’re teaching remotely, this video is invaluable.  

The video consists of my hand-written pdf file of my notes,  and as I explain each concept and example, I point an arrow to the work I’m explaining.   In the videos, I do not show my face, nor mention any names, nor show any photos, just the math is shown and my voice is heard.  Thus, this video can be used in any classroom.  All videos are in English.  When you purchase this, you will receive a zip file which includes the video and the pdf of the notes which are explained.   What you see as thumbnails for this product is the pdf file. 

I usually assign a video as homework and ask students to write down everything for their own notes.  I then check their notes as evidence that they completed the assignment- but of course, you’re welcome to use this resource in any way you want.  During in-person schooling, I have a flipped classroom and my videos are crucial to its success.  In remote learning, I use the videos for every topic I introduce, and students find them extremely helpful.  

I hope my videos can help you out too!
