I am struggling with the partial fraction decomposition of ((2l+1)(l+1))/(K+(l+1)(l+2)(l-1)), where K is a positive real number. I would like to decompose it in a sum of simpler polynomial fractions. I tried the Mathematica's function "Apart" but it is returning the fraction so I am thinking there is no simple partial fraction decomposition. Could you help me?

i think the simpliest form is this here
2 l 2 + 3 l + 1 l 3 + 2 l 2 + K l 2
