But remember, you're going down. So if you're at negative three, and you subtract one, we're going to go to the negative three minus one power. Well, that's going to take us to negative four. So this is x to the negative four power. So two times negative three x to the negative four, or we could have also written that as negative six x to the negative four power, and then minus, well, we're going to do the same thing again right over here. We take this negative two, multiply it times the coefficient that's implicitly here. You could say there's a one there, so negative two times one.
