Answer:

-1 + 6i

Step-by-step explanation:

Complex number addition  & subtraction:

Subtract/add the imaginary parts and then add real parts.

Open the parenthesis by multiplying the each term of 4 - 2i by (-1)

3 + 4i - (4 - 2i) = 3 + 4i - 4 + 2i

                       = 3 - 4 + 4i + 2i

                       = -1 + 6i
