Add (3 - 5i) + (-2 + 8i). Sum of real parts: Sum of imaginary parts: i

The correct answer is 1 + 3i.

In order to get the answer to this, only add like terms. Add first the constants in the front.

3 + - 2 = 1

Now add the imaginary terms

-5i + 8i = 3i

Then you can put the two together as a term and write as 1 + 3i.
