So, -2+-4i over 2, I can reduce that to -1+-2i, correct

you factor it out as i (which is the square root of negative 1)
therfore, your answer is
-2 + - 4i

or, if you havent learned imaginary numbers yet, just leave it as undefined

You would get -1+-2i for your answer--where i is the square root of negative 1.

(-1+2i) and (-1-2i)
where i=sqrt(-1)

There's nothing you can do, there are no real solutions to this problem
