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. So this is still just an arbitrary constant. So maybe we could have written this, if you wanted to show this as different constants you could say this is c1 c1 c1. You multiply 5 times c1 you get another constant.
