Perform the complex number multiplication: (9 - 6i)(2 - 4i)

The formula for this using the FOIL method is: (a * c) + (b * c) + (a * d) + (b * d) where:

a = 9, b = -6, c = 2, and d = -4

(9 - 6i)(2 - 4i) = (9 * 2) + (-6i * 2) + (9 * -4i) + (-6i * -4i)

(9 - 6i)(2 - 4i) = 18 - 12i - 36i + 24i

(9 - 6i)(2 - 4i) = 18 + (-12 - 36)i + 24i

(9 - 6i)(2 - 4i) = 18 - 48i + 24i

i

(9 - 6i)(2 - 4i) = 18 - 48i + 24* (-1)

(9 - 6i)(2 - 4i) = 18 - 48i - 24

(9 - 6i)(2 - 4i) = (18 - 24) - 48i

(9 - 6i)(2 - 4i) =
