11. What is the partial decomposition of \( \frac{\left(x^{2}+x+1\right)}{(x+2)\left(x^{2}+1\right)} \) \[ \begin{array}{l}\text { A, } \frac{\frac{2}{5}(x+2)+(3 x+1)}{5\left(x^{2}+1\right)} \\ \text { B, } \frac{\frac{5}{3}(x+2)+(2 x+1)}{3\left(x^{2}+1\right)} \\ \text { C, } \frac{\frac{3}{5}(x+2)+(2 x+1)}{5\left(x^{2}+1\right)} \\ \text { D, } \frac{2(x+2)+(3 x+1)}{3\left(x^{2}+1\right)}\end{array} \]
