Adding and Subtracting Radicals NF.4.AC.2: Simplify, add, subtract and multiply radical expressions Students will learn to simplify radicals and to multiply and/or divide radical expressions FHS Algebraic Connections

Adding and Subtracting Radicals To add or subtract radicals, treat them as if they were variables. You can add or subtract two variables if they are like terms. Radicals with the same radicand work the same way as variables with like terms. Here are some examples: FHS Algebraic Connections

Adding and Subtracting Radicals If the radicands are different, you cannot add or subtract them – they are not like terms You cannot add these: However, sometimes the radical expressions can be simplified and then become like terms, as in the following examples: FHS Algebraic Connections
