Respuesta :

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
hope this helped
