Use the method of partial fraction decomposition to perform the required integration. \[ \int \frac{x^{3}-3 x}{\left(x^{2}+2\right)^{2}} d x \] \[ \int \frac{x^{3}-3 x}{\left(x^{2}+2\right)^{2}} d x= \] Use the method of partial fraction decomposition to perform the required integration. \[ \int \frac{3 x^{2}+x-27}{x^{3}+9 x} d x \] \[ \int \frac{3 x^{2}+x-27}{x^{3}+9 x} d x= \]
