So let me just, the stuff that I'm going to leave the way it is, I'm just going to kind of freeze them. So the expected value of XY. Now what do we have over here? We have the expected value of X times, once again, you can kind of view it if you go back to what we just said, is this is just going to be a number, expected value of Y. So we can just bring this out. If this was the expected value of 3X, it would be the same thing as 3 times the expected value of X. So we can rewrite this as negative expected value of Y times the expected value of X.
