Aim: How do we add and subtract RADICALS? Do Now: Simplify the following radical expressions: 1. 2.

2. Recall: when we combine Like terms…
Example: 3x + -5x = Example: 10x – 25x = Example: 10x + 15 =

3. For like radicals
We can combine like radicals!

4. So now Remember When Adding and Subtracting Radicals, here are your rules
In order to add or subtract radicals, you must have “like radicals”. This means that the radicand must be the same. Remember: The radicand is what’s “inside” the radical.
