10-3A Operations with Radical Expressions Algebra 1

Simplifying expressions When adding or subtracting radical expressions, only add or subtract the coefficients if the number under the radical is the same. It’s similar to adding and subtracting like terms. You can only add or subtract the coefficients of the same radical.
