Okay. Our next one here is taking a negative three plus two times the square root of negative nine and putting this into terms of I so are negative. Three stays and then hear this nine is a perfect square. So I have to times a square root of negative one times the square root of nine. And this is I and this is three. And so here I have a negative three. That guy stays and I have a two times of three. So that's six and the eye. And you can't combine these two because they're not like terms, So this is our final answer.
