Question

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

Answer 1

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

Explanation:

`(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)`
