You could say there's a one there, so negative two times one. So you have the negative two there, and then you have the x to the, well, what's negative two minus one? Well, that's negative three to the negative three power. And so we can rewrite all of this business as the derivative g prime of x is equal to negative six, negative six x to the negative fourth, and now we're subtracting a negative, so we could just write this as plus two x to the negative three. This negative cancels out with that negative. Subtract a negative, the same thing as adding the positive. So we did the first part.
