Now I'm just going to manipulate this algebraically, so it essentially gives us this conclusion right over here. So this we can rewrite. It's important to realize that u of c, this is just going to be some value. It looks like I've kind of, maybe this is a function of x or something, but no, this is just going to be some value. I've inputted c here, and I've evaluated the function of that, and so this is going to be some number. It could be five or seven or pi or negative one, but it's just going to be some value, some constant. So I can treat it like a constant.
