1. Section 11.2B Notes Adding and Subtracting Radical Expressions Objective: Students will be able to add and subtract radical expressions involving square roots.

2. You can use the distributive property to simplify sums and differences of radical expressions when the expressions have the same radicand. Ex. ______________ The same holds true for adding and subtracting radical. If the ____________ is the same, just add or subtract the ____________. Ex. _______ radicand coefficients

4. If each radical in a radical expression is not in ________________, simplify them first by taking out any _____________________. simplest form perfect square factors

7. You can’t have a radical in denominator
