You're right, it is a conservative field - thats the key to the solution.
I think you're trying to use path independence, which is also key, but try it another way.
you're looking for the integral of F; and F = grad f.... well... whats the integral of grad f?

The only thing you are doing wrong is that you have not finished the problem!

You have (9- 12+ 4)- (1/4+ 1- 1). Okay, what number is that?

Well, that answer is 3/4, but the answer in the back of the review has -27/4.
