RadicalsA square root symbol is also known as a radical sign. The number inside the radical is the radicand.To simplify a radical, find the largest perfect square factor of the radicand32 =16 × 2Take the square root of that number and leave any remaining numbers under the radical.32 =42To add or subtract square roots, you must have like terms. In other words, the radicand must be thesame. If you have like terms, simply add or subtract the coefficients and keep the radicand the same.
