Question

Add . (4+2i) + (4-5i) ?

Answer 1

When we add two of the same number together, this is the same as multiplying by 2. For this problem, let's convert (4 + 2i) + (4 + 2i) into
`2(4 + 2i)`.

After this step, we do something called distributing, so you multiply 2 by the number inside:

`2(4 + 2i) = 8 + 4i`.

Hope this helped.
