Answer:
See proof below
Step-by-step explanation:
Let 
. If w=-z, then r=0 and r is real. Suppose that w≠-z, that is, r≠0.
Remember this useful identity: if x is a complex number then 
where 
is the conjugate of x.
Now, using the properties of the conjugate (the conjugate of the sum(product) of two numbers is the sum(product) of the conjugates):
=
Thus 
. From this, 
. A complex number is real if and only if it is equal to its conjugate, therefore r is real.
