Week 4 – Adding and Subtracting Radical Expressions

This week I learned how to add and subtract radical expressions.

This is a question I was stuck on:

In simplifying this problem you need to add together all the sides of the shape formed. When doing this you need to first simplify \sqrt{50} and then \sqrt{24}. Then you add the common radicands together to simplify the problem. I had trouble realizing that the roots were the values for the sides of the shape.
