Answer:
11.2x
Step-by-step explanation:
You simplify it by doing distributive property like this
(4+2i)(3-i) =12-4i+6i-2i2
now add common like numbers
12+2i-2i2
Now on the i that is squared change the i to a -1 and get this
12+2i+2
Now again add common like numbers and get
14+2i that would be your answer
