Differentiate the function.

$y=\frac{9x^2-2}{3x^{3}8}$

B$.y^{\text{'}}=\frac{(3x^{3}8)(\frac{d}{dx}(9x^2-2))-(9x^2-2)(\frac{d}{dx}(3x^{3}8))}{(3x^{3}8)}$

C$.y^{\text{'}}=(3x^{3}8)(\frac{d}{dx}(9x^2-2))-(9x^2-2)(\frac{d}{dx}(3x^{3}8))$

D$.y^{\text{'}}=\frac{(9x^2-2)(\frac{d}{dx}(9x^2-2))-(3x^{3}8)(\frac{d}{dx}(3x^{3}8))}{(3x^{3}8{)}^2}$

The derivative of $y=\frac{9x^2-2}{3x^{3}8}$ is
