"Cancellation" refers to dividing the top and bottom of a fraction by a common multiplicative factor. There are no common factors of the top and bottom of that fraction. Presumably you want to do something like get rid of the 'b' from top and bottom, but think about this: what if the fraction was (i.e. 8/4, which is 2)? Would you be able to get rid of the 6 from top and bottom to get (i.e. -1)?
