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

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

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

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

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