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: 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: Algebraic Connections
