Dec 15, 2024 · Subtraction of radicals follows the same set of rules and approaches as addition: the radicands and the indices (plural of index) must be the same for two (or more) radicals to be subtracted.

Jul 23, 2025 · Adding and subtracting radicals involves combining radical expressions with the same index and radicand. In this article, let's learn about the addition and subtraction of square roots in detail.

To simplify radical expressions, the key step is to always find the largest perfect square factor of the given radicand. Next, break them into a product of smaller square roots, and simplify.

Adding and subtracting radicals: For radicals having the same index (root) and the same values under the radical (the radicands), add (or subtract) the values in front of the radicals and keep the radical.
