%28%28sqrt%28a%29+%2B+sqrt%28b%29%29%29%2F%28%28sqrt%28a%29-sqrt%28b%29%29%29
Multiply by the conjugate of the bottom over itself, which is just 1 so it won't change the value: red%28%28%28sqrt%28a%29+%2B+sqrt%28b%29%29%29%2F%28%28sqrt%28a%29%2Bsqrt%28b%29%29%29%29

%28%28sqrt%28a%29+%2B+sqrt%28b%29%29%29%2F%28%28sqrt%28a%29-sqrt%28b%29%29%29%22%22%2A%22%22red%28%28%28sqrt%28a%29+%2B+sqrt%28b%29%29%29%2F%28%28sqrt%28a%29%2Bsqrt%28b%29%29%29%29

USE "FOIL"


++%28a%2B2sqrt%28ab%29%2Bb%29%0D%0A%0D%0A%2F%28a-b%29+
