    (6 + 3i) (6 + 3i) = 6*6 + 6*3i + 6*3i + 9i^2

    = 36 + 36i + 9*-1

    = 36 + 36i - 9

    = 27 + 36i

    (6 + 3i) (6 - 3i) = 6² - (3i) ² = 36 - 9i² = 36 + 9 = 45

    (4 - 5i) (4 + 5i) = 4² - (5i) ² = 16 - 25i² = 16 + 25 = 41

    (-3 + 8i) (-3 - 8i) = (-3) ² - (8i) ² = 9 - 64i² = 9 + 64 = 73
