2. 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:

3. 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:
