Determine the open intervals on which the graph is concave upward or concave downward. (Enter your answers using interval notation. If an answer does not exist, enter DNE.) f(x)=(x^2 +8)/(x^2 -1)

I've gotten to the 2nd derivative, but I'm confused about where to go from there. Any help would be rad! Cheers!
