Hi

Can someone tell me if my answer is correct or my book's answers

1) Resolve into a partial fraction: $\displaystyle \frac{x+1}{(x^2+4)(x^2-1)}$

i got $\displaystyle \frac{\frac{1}{5}}{(x-1)}-\frac{\frac{1}{5}}{(x^2+4)}$

however book's answers is $\displaystyle \frac{\frac{1}{5}}{(x-1)}-\frac{(x+1)}{5(x^2+4)}

$

P.S
