The answer to this is C. (28,10) and (22,2).
Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL
(3-2i)(1+7i)
3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers
3+19i+14
17+19i or C
Answer:
D) 72 is correct because 8 times 9 is 72! Hope this helped. :)
