$5$ of $9$

Differentiate the function.

$y=\frac{2x^2-5}{6x^{3}7}$

Which of the following shows how to find the derivative of $f(x)?$

A$.y^{\text{'}}=\frac{(2x^2-5)(\frac{d}{dx}(2x^2-5))-(6x^{3}7)(\frac{d}{dx}(6x^{3}7))}{(6x^{3}7{)}^2}$

B$.y^{\text{'}}=\frac{(6x^{3}7)(\frac{d}{dx}(2x^2-5))-(2x^2-5)(\frac{d}{dx}(6x^{3}7))}{(6x^{3}7)}$

C$.y^{\text{'}}=(6x^{3}7)(\frac{d}{dx}(2x^2-5))-(2x^2-5)(\frac{d}{dx}(6x^{3}7))$

D$.y^{\text{'}}=\frac{(6x7)(\frac{d}{dx}(2x-5))-(2x-5)(\frac{d}{dx}(6x7))}{(6x^{3}7{)}^2}$

The derivative of $y=\frac{2x^2-5}{6x^{3}7}$ is
