1. Adding & Subtracting Radical Expressions

2. Objective - To simplify radical expressions involving addition & subtraction.

3. Adding & Subtracting Radicals
Remember yesterday we learned how to simplify radicals:
1) No perfect square factor in a radical.
2) No fractions or decimals in a radical.
3) No radicals in a denominator.
SIMPLIFY FIRST!

4. Adding & Subtracting Radicals
Adding and subtracting radicals is the same as combining like terms.
Like radicals have the same root and radicand.
To combine like radicals, just add/subtract the “coefficients”!
