Answer 1

♡ Answer

complex number such as 5+2i is made up of two parts, a real part 5, and an imaginary part 2. The imaginary part is the multiple of i. It is common practice to use the letter z to stand for a complex number and write z = a + bi where a is the real part and b is the imaginary part.

Answer 2

Step-by-step explanation:

After multiplier

-3i² - 2i

3-2i ( i² is -1)

So , imaginary part is -2
