Presentation transcript:

Adding and Subtracting Radicals

1. Simplify. 2. Simplify. Which are like radicals? Just like when adding variables, you can only combine LIKE radicals. Think : 3x + 4x - 2x = 5x 2. Simplify. Which are like radicals?

Simplify .

Perimeter = Add all of the sides 3. Find the perimeter of a rectangle whose length is and whose width is Perimeter = Add all of the sides

Then combine like radicals. 4. Simplify. Simplify each radical. Then combine like radicals.

5. Simplify

Simplify .

Simplify .
