Question

How do you simplify `(-4 - 6i) + (-2 - 3i)` and write in a+bi form?

Answer 1

`-6-9i`

Explanation:

Treat the imaginary `i` just like you would an `x`.

`(-4-6i)+(-2-3i)`

`-4-6i-2-3i`

`-4-2-6i-3i`

`(-4-2)+(-6i-3i)`

`-6-9i`

Notice that this is in `a+bi` form: the term without the `i` comes first.
