So if we do that, then this is going to become 1 5th times 1 4th, which is going to be 1 20th times the integral of one over x minus three squared over two squared. And then this is going to be a plus one. And of course, we have our dx. And then we could write this as, and I'm trying to just do every step here. A lot of these you might have been able to do in your head. One over, and I'll just write this as x minus three over two squared plus one. Plus one, and then dx.
