Is it possible to factor 1+x^5?
Or to integrate
(x^2)/(1+x^5)?
Thanks

The sum of two terms to the same odd power can always be factored. Since 1 = 1^5, you factor it into
(1 + x)(1 - x + x^2 - x^3 + x^4)
Not sure how that helps to integrate though...
Note: wow, the integrator on line gives a ridiculous answer - check it out:

We use the coeffiecent of the 1st and final term to be sure the achieveable zeros, the place "p" are all the integer aspects of final term's coefficient and "q" is the aspects of the 1st term. So, -12 aspects into: a million,2,3,4,6,12,-a million,-2-3,-4,-6,-12. the aspects of our first term are: a million,-a million So the achieveable rational zeros are: a million,2,3,4,6,12,-a million,-2-3,-4,-6,-12 (many times notated with a 'plus/minus' sign somewhat of itemizing the valuable and detrimental values seperately.)
