Quotient Rule

Hey guys,

Looking for help here again,

I have the function: F(x): (x^2-4)/(x+1). We are supposed to use the quotient rule. I cannot seem to get the correct answer at the back of my book..

I get: (2x+4)/(x+1)^2

Textbook: 3/(2x+1)^2

What am I doing wrong?

Re: Quotient Rule

I worked that one out previously...I was not sure..My textbook has been sub-par for providing us with the right answers..I have 100% more confidence in going with yours.
