Answer 1

4. Simplify the expression: (3-i)-(2+6i)

First, take that minus sign in the middle and distribute it to the (2+6i)

You will get 3 - i -2 - 6i

Combine like terms. (the i's can combine)

So combine the 3 and the -2 to get 1

Combine the -i and the -6i to get -7i

Together, you have 1 - 7i
