There are 2 questions involving derivatives that I have trouble getting to the answer for. The first one is $\displaystyle y = [(6-5x) / (x^2 - 1)]^2$

and the 2nd one is

$\displaystyle y = 36 / (3-x)^2$

The answers respectively are;

$\displaystyle [2(6 - 5x)(5x^2 - 12x + 5)] / (x^2 - 1)^3$

&

$\displaystyle y = (8/3)x + 4$

It would be very much appreciated if anyone could provide step-by-step solutions to both problems.
