unfortunately the giving of complete answers is forbidden.
you need to use the quotient rule:
{V*du/dx - U*dv/dx}/V2

What is your working so far?

Again - USE the reply button on the post you are replying too - you will get a quicker response
What did you get when you differentiated u and v
I used reply bottom but it doesn't work, why?

When you differentiate v, (2x-1)^3 , you get 6(2x-1)^2, not 6(2x-1)
This caused your simplifying to go wrong, when you were cancelling down the fraction.

Because you are not replying to the post - use the button on the post rather than the one under the posts
