Simplifying
To simplify , recognize that both terms share the identical radicand and are therefore like square roots. You can combine them by subtracting their coefficients, exactly as you would with algebraic like terms. Compute , and keep the radical unchanged to get . This illustrates how subtracting a larger coefficient from a smaller one results in a negative coefficient, just as .
