(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a) Differentiate y=((x-1)/(x+1))^2

b (non calculus simplification question):

How would i simplify 10(5x+3)(5x-1)+5(5x-1)^2 to get 25(5x-1)(3x+1)

should i expand all terms then combine and factor?

2. Relevant equations

3. The attempt at a solution

a) i tried using the quotient rule but kept ending up with missing terms...

from the answer key i know that the answer is (4(x-1))/(x+1)^3

but i can't get that for the life of me...
