I want to split the fraction:
2a/((a+1)(a2+4))
I have tried using partial fractions, but came to something that was nonsense, and my question is why that is. Why doesn't partial fractions work in this case, from a mathematical point of view, and is it still possible to split up the fraction?
----------------------------------
Chances are of course that I just used partial fractions the wrong way, so here is how I did:
2a/((a+1)(a2+4)) = C/(a+1) + D/(a2+4)
we have that:
C(a2+4) + D(a+1) = 2a
Which gives us the equations:
Ca2 = 0
4C + D = 0
Da = 2a
which clearly contradict each other. What is wrong in my approach?
2a/((a+1)(a2+4))
