For this case we have the following expression:
[tex] (-3 + 6i) (- 3 + 5i)
[/tex]
To solve the problem, we apply the distributive property.
We have then:
[tex] (9 - 15i) + (-18i + 30i ^ 2)
[/tex]
Rewriting we have:
[tex] 30i ^ 2 -33i + 9
30 (-1) -33i + 9
-30 -33i + 9
-33i - 21
[/tex]
Therefore, the answer for this case is:
[tex] -21-33i
[/tex]
Answer:
-21-33i
Note: review the options again. The answer does not seem to be among the options.
