3. Conjugates
Many rational quotients have a sum or difference of terms in a denominator, rather than a single radical.
need to multiply by the conjugate of the denominator
The conjugate uses the same terms, but the opposite operation (+ or ).

4. If the denominator contains a radical and it is not a monomial term, then the use of a conjugate is required.
