Answer:
13
Step-by-step explanation:
1. Distribute each term in the first binomial to each term in the second binomial, FOIL (first, outer, inner, last)
(3 - 2i) (3 + 2i)
9 + 6i - 6i - [tex]4i^{2}[/tex]
2. Simplify
9 - [tex]4i^{2}[/tex]
3. Solve for i. [tex]i^{2}[/tex] = -1
9 - 4 (-1)
9 + 4 = 13
hope this helps!
