That means the order of addition does not affect the final value. Otherwise, we just have to keep them unchanged. Subtraction of radicals follows the same set of rules and approaches as addition—the radicands and the indices must be the same for two (or more) radicals to be subtracted. Adding radical expressions with the same index and the same radicand is just like adding like terms. Next, break them into a product of smaller square roots, and simplify. 0000014411 00000 n � :H�lxIQ�C� N�+��)���>���@G�q��+�����:��d3� 2��u�8u4xh!Oi8G^a�Q�oj�-��v��璀~ �'� Simplifying radical expressions (subtraction) Simplifying radical expressions: two variables.
