Now what could I add, and then I'm gonna have to subtract if I don't wanna change the value of the denominator, in order to make this part right over here a perfect square? Well, we've done this before. You take half of your coefficient here, which is negative three, and you square that. 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.
