So, the left-hand side right over here, and you might be able to do that in your head. You say, hey, look, you have w minus 300. Its derivative is one, so it's essentially there. So, I can just take this as if this was one over, I can just take the antiderivative here and treat this whole thing as kind of a variable. So, it would just be the natural log of this entire thing, or the absolute value of that entire thing. So, the integral of the left-hand side is the natural log of w minus 300, of the absolute value of w minus 300. And the derivative of the right-hand side, and this is a little bit more straightforward, with respect to t, or sorry, the antiderivative with respect to t on the right-hand side is one over 25t, or we could say t over 25.
