Step-by-step explanation:
![(-3+3i)(-2+3i)](https://tex.z-dn.net/?f=%28-3%2B3i%29%28-2%2B3i%29)
Multiply the parenthesis. multiply each term in first parenthesis with each term in second parenthesis.
![(-3+3i)(-2+3i)](https://tex.z-dn.net/?f=%28-3%2B3i%29%28-2%2B3i%29)
![-3(-2+3i)+3i(-2+3i)](https://tex.z-dn.net/?f=-3%28-2%2B3i%29%2B3i%28-2%2B3i%29)
![6-9i-6i+9i^2](https://tex.z-dn.net/?f=6-9i-6i%2B9i%5E2)
The value of i^2 is -1
