Partial Fraction Decomposition with an irreducible denominator How can you use PFD (Partial Fraction Decomposition) to solve this integration problem? I can normally do these fine with denominators that factor, but this one doesn't seem to be able to do that.
$$
\int_0^2\frac{2x^2+x+8}{x^4+8x+16} \mathrm{d}x
$$
Could I set it up as $\displaystyle\frac{Ax^3+Bx^2+Cx+D}{x^4+8x+16}$ and then find the values of $A$,$B$,$C$, and $D$ to complete the integration?

Hint: assuming the denominator should be $(x^2+4)^2,\:$ rewrite the numerator as $\rm\:2\:(x^2+4) + x$. Then each summand/denom integrates easily, viz. an arctan + rational function. 
Almost surely this was what was intended since the numerator has form that enables said easy partial fraction decomposition when the denominator is as speculated.
