Answer 1

the answer is the first one not the third one, first one has a - whereas the third one has a +

Explanation:

I took the test and i got it right

Answer 2

using the quotient rule

dy/dx = (x^-1) * (3x^2 -5 ) - (x^3 - 5x) * 2x
----------------------------------------------
(x^2 - 1)^2

You are correct
