1. Adding and Subtracting Radicals ***Simplifying Radicals WS Due*** BELL WORK- To turn in

2. Adding and Subtracting  To multiply or divide radicals they have to have the same index (the little number before the root symbol)  To add or subtract radicals they have to have the same index AND the same radicand (the number under the root symbol)

3. Ex. 1:

4. Ex. 2:

5. Ex. 3: Find the exact measure of the perimeter of the rectangle.

6. IMPORTANT  If each radical in a radical expression is not in simplest form, simplify them first.  Then use the distributive property, whenever possible, to further simplify the expression.

7. Ex. 4:  (Let’s do this part on the white board)

8. Ex. 5: Simplify

9. Ex. 6: Simplify.

10. Time to work! 1)Simplify the radicals if needed 2)Combine like terms (ones where the radical has the same index and radicand)
