Hi! What we are doing is to assumed the format of individual proper rational expressions that, when combined, will give the original rational expression asked by the question. So while still in the different partial fraction formats that we are assuming, the unknown coefficients will be these "arbitrary constants" you are referring to.
very helpful
why we use unknown arbitrary constants in the solution of partial fraction?
