Homework Statement
Find the derivative of (x^2-x^-1+1)(x^3+2x-6)^7
Homework Equations
This is a product so I used the product and chain rule where appropriate
The Attempt at a Solution
(x^3+2x-6)[7(x^2-x^-1+1)(3x^2+2)]+[(x^3+2x-6)(2x+1/x^2)]
This is as far as I could get in my simplification. My book has an answer which is further simplified. I now that I must know combine the two bracketed factors but when I do this my answers doesn't equal my text's answer. I'm usually fine with the algebra involved in simplifying but I simply do not see where my error lies.
This is one of my first higher level math courses and I'm really trying to solidify the skills being introduced.
