So we're gonna evaluate it at negative two and we're going to evaluate it at negative one. So let's first evaluate it at negative two. So this is going to be equal to, this is going to be equal to, when you evaluate it at negative two, it's going to be negative eight, negative eight times x to the negative two, so negative two to the negative two power, minus negative two, and from that we're going to subtract it, evaluate it at negative one. So it's going to be negative eight times negative one to the negative two power, minus negative one. Alright, so what is this going to be? So negative two to the negative two, so negative two to the negative two is equal to one over negative two squared, which is equal to 1 4th. So this is equal to positive 1 4th, but then negative eight times positive 1 4th is going to be equal to negative two, and then we have negative two minus negative two, so that's negative two plus two, and so everything I've just done in this purplish color, that is just going to be zero, and then if we look at what's going on in the orange, when we evaluate at negative one, let's see, negative one to the negative two power, well that's one over negative one squared, well this is all just going to be one, and so we're going to have negative eight plus one, which is equal to negative seven.
