Conjugate

#### Explanation:

Just to add on to the other answers,

We decided to multiply the top and the bottom by **conjugate of the denominator**,

A conjugate is an expression in which the sign in the middle is reversed. If (A+B) is the denominator, then (A-B) would be the conjugate expression.

When simplifying square roots in the denominators, try multiplying the top and bottom by the conjugate. It will get rid of the square root, because **squared**.
