SUMMARY

The discussion focuses on applying the quotient rule to find the derivative of the function y = (2x-3)/(√(x^2-5)). Participants clarify the correct interpretation of the function's components and the proper use of parentheses to avoid confusion. The final derivative is confirmed as y' = (3x - 10)/(x^2 - 5)^(3/2), ensuring all steps are accurately followed and simplified. Key corrections include the proper identification of f(x), g(x), and their derivatives, f'(x) and g'(x).

here is my new answer i am steaming -3x-10 / x^2-5

I think 3x-10 is correct for the numerator, unless I also made an algebra mistake somewhere. But you need to fix the denominator.

yep its y'= 3x-10 / root(x^2-5)^3. Thanks you soooo much.

You need parentheses for the terms in the numerator. Also, mixing "root" and the exponents looks pretty weird (not wrong, though).

y' = (3x - 10)/(x2 - 5)^(3/2)
