Answer:

I got -6 + 2i

Step-by-step explanation:

(3-5i)(-2+4i)

So we would multiply the following:

3*-2 = -6

3*4i =12i

-5i*-2 = 10i

-5i * 4i = -20i

Therefore the expression would be

- 6 + 12i + 10i - 20i

we then would add and subtract the variables, which would be

-6 + 2i

I hope this helps! Have a nice day!
