Hello, I am stumped on how to differentiate this function:
(1+x) / x^4
My attempt is:
1(x^4) - (1+x)4x^3
= (x^4 - (4x^3+4x^4)) / x^8
= ((-4x^3)-4) / x*
at this point I am not sure if I am headed in the right direction.
Thanks for any help.

Please make an effort to learn latex - your post is extremely difficult to follow.
We get $\displaystyle f'(x)=\frac{(x^4) - (1+x)4x^3}{x^8}$
$\displaystyle =\frac{(x^4) - 4x^3-4x^4}{x^8}$
$\displaystyle =\frac{-4x^3-3x^4}{x^8}$
Now, as far as I can see, once you divide through a common factor, you're done.
