derivative of

f (x) = \frac{x ^{2} - 2 x - 3}{x}

\frac{x ^{2} + 3}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2} - 2 x - 3}{x})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( x ^{2} - 2 x - 3 ) x - \frac{d x}{d x} ( x ^{2} - 2 x - 3 )}{x ^{2}}

\frac{d}{d x} (x^{2} - 2 x - 3) = 2 x - 2

\frac{d x}{d x} = 1

= \frac{( 2 x - 2 ) x - 1 \cdot ( x ^{2} - 2 x - 3 )}{x ^{2}}

Simplify

\frac{( 2 x - 2 ) x - 1 \cdot ( x ^{2} - 2 x - 3 )}{x ^{2}} : \frac{x ^{2} + 3}{x ^{2}}

= \frac{x ^{2} + 3}{x ^{2}}
