So you wanna add a nine here. But if you add a nine, then you have to subtract a nine as well. And so this part is going to be x minus three squared. And then this part right over here is going to be equal to a positive four. And we of course don't wanna forget our dx out here. And so let me write it in this form. So this is going to be equal to 1 5th times the integral of one over, get myself some space, x minus three squared plus four, which could also write as plus two squared.
