Question

Please simplify 9/3-2i.

Answer 1

3-2i is as far as you can simplify

Answer 2

i = sqrt -1

Multiply by 3+2i/3+2i

combine: 9(3+2i)/(3−2i)(3+2i)

foil: 9(3+2i)/3⋅3+3(2i)−2i⋅3−2i(2i)

simplify: 9(3+2i)/9−4i^2
9(3+2i)/9+4
9(3+2i)/13
27+18i/13
Divide each term in the numerator by the denominator.

27/13+18i/13 = answer
