So this over here is going to be x over y. And so now we just have to simplify this expression. This is going to be equal to, and I'll try to do it part by part, that part right over there is just going to be a one over y. And then all of this business, let's see if I can simplify that, this negative is going to go out front, so minus. And then I'm gonna have x times x in the numerator, and then it's going to be divided by y squared and then divided by another y. So it's going to be minus x squared over y to the third, over y to the third. Or another way to think about it, x squared times y to the negative three.
