Answer:
[tex]33+4i[/tex]
*None of the answer choices are correct. It's most plausible that your teacher forgot to regard [tex]i=\sqrt{-1}[/tex] and got [tex]\text{d. }9+4i[/tex]. I'd recommend choosing this answer and talking about it with your teacher later.
Step-by-step explanation:
Recall that [tex]i=\sqrt{-1}[/tex].
Solving, we get:
[tex](3-2i)(7+6i),\\21-14i+18i-12(-1),\\21-14i+18i+12,\\\boxed{33+4i}[/tex]
