2. (5+3i)-(-4+2i)
(5+4)+(3i-2i)Answer 9+i
3.(2-4i)(3+i)
6-10i-4(-1)=6-10i+4 Answer 10-10i
4. (2-4i)/(3+i)
(2-4i)/(3+i)Answer -4i+2/i+3
5. (1-i)(3+2i)

You can put this solution on YOUR website!
#1,#2, #3 and 5 are fine
#4 1/5-(7 i)/5=0.2 -1.4 i in decimal form
BTW even your wrong answer -4i+2/i+3 can be reduced even more to 3-6i
