And now we can just use, I guess we could call it this anti-power rule. So this is going to be equal to 5 times x to the negative 2 power plus 1 over the negative 2 power plus 1 plus some constant right over here. And then we can rewrite this as 5 times negative 2 power plus 1 is x to the negative 1 over negative 2 plus 1 is negative 1 plus some constant. And this is equal to 5 times negative x to the negative 1 plus some constant. And then if we want we can distribute the 5. So this is equal to negative 5 x to the negative 1. Now we could write plus 5 times some constant but this is just an arbitrary constant.
