Here was my attempt it was actuly a derivative problem but i decided not to post in the calculus section.

You can't distribute the two to the binomial expression because that expression is an infinite sum and the 2 is not raised to the same power.

You cannot simplify that further.

**EDIT**: If you're planning on finding the derivative use the product rule and the chain rule :) - Feb 20th 2010, 12:13 PMicemanfan
I'm assuming you are taking the derivative of f(x):

In that case, you made errors in both the second and third steps.

(second step) You can't put the multiple of 2 inside the term.

(third step) You should be multiplying by , not subtracting . - Feb 20th 2010, 12:14 PMx5pyd3rx
