Question

How do you simplify `(-2-6i)-(4-6i)`?

Answer 1

`(-2-6i)-(4-6i)=-6`

Explanation:

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

= `-2-6i-4+6i` - as we have a minus sign outside we have changed all the signs inside as it is equivalent to multiplying by `-1`.

Hence above is equivalent to

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

= `-2-4`

= `-6`
