Well, that would be one over u squared plus one. So this is going to be equal to 1 1 0 times the arc tangent of u. And of course, we can't forget our big constant c, because we're taking an indefinite integral. And now we just wanna do the reverse substitution. We know that u is equal to this business right over here, so we deserve a little bit of a drum roll. This is going to be equal to 1 1 0 times the arc tangent of u. Well, u is just x minus three over two, which could also be written like this.
