2. Adding and Subtracting Radicals
Radicals that represent the square root of the same number can be treated as a common factor.
Examples:
Radicals representing square roots of different numbers can not be gathered like this.
But simplifying sometimes results in multiples of the same radical, which can be.
Examples:
Like terms can be gathered. Unlike terms can not.

3. Radicals ARE simplified
Simplify radicals if possible
Combine coefficients
Radicals ARE simplified

4. Just like when adding variables, you can only combine like radicals.

6. Practice

7. Simplify each radical. 4√9•3 - 2√16 • 3 + 2√4•5
4 • 3√3 - 2 • 4√3+2 • 2√5
12√3 - 8√3 + 4√5
4√3 + 4√5
