Answer:


33+4i

*None of the answer choices are correct. It's most plausible that your teacher forgot to regard
i=√(-1) and got
\text{d. }9+4i. I'd recommend choosing this answer and talking about it with your teacher later.

Explanation:

Recall that
i=√(-1).

Solving, we get:


(3-2i)(7+6i),\\21-14i+18i-12(-1),\\21-14i+18i+12,\\\boxed{33+4i}
