1. Unit 3 Lesson 1 Part 1 Operations involving radical expressions Adding and Subtracting!

2. Adding and Subtracting Radicals
Suppose we are given the following problem:
In order to combine radicals, we must treat the radicals like variables.

3. Adding and Subtracting Radicals
We will add the coefficients in front of the radical symbols.

4. Adding and Subtracting Radicals
Let’s try another problem….
This time we need to identify like terms.

5. Adding and Subtracting Radicals
Let’s rewrite the expression so that all like radicals are next to each other. Remember to keep the sign as you rearrange the expression.

6. Adding and Subtracting Radicals
Let’s combine like terms…

7. Adding and Subtracting Radicals
One more time….

8. Summary Make sure you… Treat the radicals as if they are variables
Combine like radicals just as you would variables
