Well, that's negative x squared over two, and then we have the negative two, or so the antiderivative is negative two x. We're gonna evaluate that at negative, at negative two and negative four. And so that part is going to be what? Negative two squared, so it's the negative of negative two squared. So it's negative four over two minus two times negative two, so plus four. So that's it evaluated at negative two. And then minus, if we evaluated it at negative four, so minus, so we're gonna have minus, negative four squared is 16 over two minus two times negative four.
