I am going to evaluate it at 10, and subtract from that, and evaluate it at 0. And so this is going to be equal to 1 tenth, that same 1 tenth there. And when you evaluate all of this at 10, what are we going to get? Let's see, 10 to the fourth power is 10,000 divided by 4 is 2,500. And then minus 2 times 10 to the third, so it's 2 times 1,000. So minus 2,000. And then 300 times 10, well that's plus 3,000.
