Combine the Real and Imaginary components independently to get
$(2 - 4 i)$ $(2-4i)$

$(8 - 8 i) - (6 - 4 i)$ $(color(red)(8)-color(blue)(8i))-(color(red)(6)color(blue)(-4i))$

$Real components X 8 - 6 = 2$ $color(red)("Real components") color(white)("X")color(red)(8 - 6 = 2)$

$Imaginary components X - 8 i - (- 4 i) = - 4 i$ $color(blue)("Imaginary components")color(white)("X")color(blue)(-8i-(-4i) = -4i)$

How do you combine (8-8i) - (6-4i) (8−8i)−(6−4i)(8-8i) - (6-4i) ?
