So we'll put negative x squared plus 8x minus 16. So I'm just going to add the negative of this. And we get, and I'll do this in a new color, let's see, we get x to the fourth minus 4x to the third power minus 5x squared plus 24x. And then these cancel out. So that's what we are left with. And so that's the inside of our integral. So we're going to take the integral of this thing, just so I don't have to keep rewriting this thing, from 0 until, if I remember correctly, 3.
