Question 253915
i came up with 11 - 2i


here's how.


multiply (4-3i) * (2+i)


4 * 2 = 8
4 * i = 4i
-3i * 2 = -6i
-3i * i = -3i^2


add them up together and you get:



8 + 4i - 6i - 3i^2


combine like terms to get:


8 - 2i - 3i^2


since i^2 = -1, this becomes:


8 - 2i - 3*(-1) which becomes:


8 - 2i + 3


combine like terms to get:


11 - 2i


that would be selection 4.
