Homework Statement
[tex]\int\frac{4x^5-1}{(x^5+x+1)^2}dx[/tex]
Homework Equations
This is in the section on Partial Fractions. The main idea in this section was that you get the integral down to a sum integrals of the following forms:
[tex]\int\frac{dx}{(x+a)^n} , \int \frac{x dx}{(x^2 + bx + c)^m} , \int \frac{dx}{(x^2+bx+c)^m}[/tex]
The Attempt at a Solution
The basic approach for most of these was to just use partial fractions by factoring the denominator and algebraically breaking down the result. I factored the denominator to
[tex]\left(x^2+x+1\right)^2\left(x^3-x^2+1\right)^2[/tex]
The term on the right could be factored again, but it doesn't look promising.
I sense I should be using a different approach with this problem, but I'm not sure what.
Please just give me a hint, if possible.
