It's really not that hard to find. I just tried searching the 
Documentation for "complex numbers".

The first two hits are "Complex" and "Numbers".

The third on the list, highlighted with a nice orange bullet, is 
"Complex Numbers". This takes you directly to guide/ComplexNumbers, 
which has all the basic functions for working with complex numbers, 
including this:

ComplexExpand -- expand symbolic expressions into real and imaginary parts

Seems pretty clear to me.
