Step 1

Differentiate using the Quotient Rule which states that $\frac{d}{d x} [\frac{f (x)}{g (x)}]$ is $\frac{g (x) \frac{d}{d x} [f (x)] - f (x) \frac{d}{d x} [g (x)]}{{g (x)}^{2}}$ where $f (x) = 3 x^{2} - 8 x - 3$ and $g (x) = 4 x^{2} - 6 x + 6$ .

Step 2.1

By the Sum Rule, the derivative of $3 x^{2} - 8 x - 3$ with respect to $x$ is $\frac{d}{d x} [3 x^{2}] + \frac{d}{d x} [- 8 x] + \frac{d}{d x} [- 3]$ .
