And then du is going to be equal to dx. And so this is going to be, we can rewrite in terms of u as two, I'll just take the constant out, two times the integral of one over u du, which we know is two times the natural log of the absolute value of u plus c. And in this case, we know that u is x minus one. So this is equal to two times the natural log of x minus one plus c. And so that's what we're gonna have right over here. So plus two times the natural log of the absolute value of x minus one plus c. And the plus c doesn't just come from this one. This, in general, when we're taking the integral of the whole thing, there could be some constant, because obviously if we go the other way, we take the derivative, the constant will go away. So let me just put the plus c right over there. And we are done.
