(2 + 3i)/(3 -3i) (2 + 3i)/(3 -3 i)
= [(2 + 3i)/(3 -3 i)] ● [(3+3i)/(3+3i)]
[(2 + 3i)/(3 -3 i)] ● [(3+3i)/(3+3i)] =
(6 + 6i + 9i + 9i2)/(9 +9i-9i - 9i2)
(6 + 6i + 9i + 9i2)/(9 +9i-9i - 9i2) =
(6 + 6i + 9i - 9)/(9 +9i-9i +9)
(6 + 6i + 9i - 9)/(9 +9i-9i +9) = (-3 + 15i)/18
(-3 + 15i)/18 = -3/18 + 15/18
