It's already simplified. Do you want to rationalize the denominator?

OpenStudy (anonymous):

idk

Well, there isn't much else to do with it, so lets rationalize the denominator (that meas to get a non-irrational or non-complex number on the bottom). Quick and cheap way to do that is to multiply by 1. But you can express '1' as the conjugate of the denominator divided by itself. The conjugate of a complex number, a+bi is a-bi, so in your example, multiply top and bottom by 1+i.
