Question

How do you simplify `(5 + 2i ) - ( 2 + 3i )`?

Answer 1

`3-i`

Explanation:

If we begin with `(5+2i)-(2+3i)`, the first step is to multiply the `-1`
into the `2+3i` parentheses, which becomes `5+2i-2-3i`. From here we just combine like-terms, like `5` and `-2`, as well as `2i` and `-3i`. This leaves us with `3-i`.
