## Homework Statement

Find the derivative of y= x^2 (x^2 - 1)^3 (x+1)^4 using logaritmic differentiation.

## Homework Equations

## The Attempt at a Solution

y= x^2 (x^2 - 1)^3 (x+1)^4 = 2 ln|x| + 3 ln |(x^2)-1|+ 4 ln |x+1|

2/x + (6x)/(x^2-1) + 4/(x+1)

Is this right and if so what should I do next?

Thanks a lot in advance..
