And then finally, v of x we know is x squared plus three x. So this is x squared plus three x. And so what do we get? Well, we are going to get, and it's gonna look a little bit hairy, it's going to be equal to negative, I'll focus, so first we have, first we have this business up here. So it's negative three times x squared plus three x. So I'm just gonna distribute the negative three. So it's negative three x squared minus nine x.
