Question

The product of (3 2i) and a complex number is (17 7i) What is the complex number.

Answer 1

(I'll assume that the blank spaces are PLUS signs ( + ),
as they usually are on Brainly.)

The mystery complex number is  (5 - i) .

     (3 + 2i) x (5 - i)  =  (17 + 7i)

FOIL it out and you'll see it.
