I have been working on derivatives, but now the homework problem's "show example" skips to immediately finding the derivative and every time I am getting a different answer. The original equation is y=((x-3)/(x+1))^2. The derivative is (8x-24)/(1+x)^3. My answer was (2x-6)/(x+1)^3. I am not understanding where the multiplication of 4 comes into play, this section is on the chain rule and that's what I assumed I had applied but clearly something is wrong. I can no longer use this problem, the website creates a similar problem when I've used the "solve this".
