\frac{d}{d x} (\frac{x ^{2} - 8 x + 4}{2 x})

\frac{x ^{2} - 4}{2 x ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2} - 8 x + 4}{2 x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{2} \frac{d}{d x} (\frac{x ^{2} - 8 x + 4}{x})

Apply the Quotient Rule:

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

= \frac{1}{2} \cdot \frac{\frac{d}{d x} ( x ^{2} - 8 x + 4 ) x - \frac{d x}{d x} ( x ^{2} - 8 x + 4 )}{x ^{2}}

\frac{d}{d x} (x^{2} - 8 x + 4) = 2 x - 8

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

= \frac{1}{2} \cdot \frac{( 2 x - 8 ) x - 1 \cdot ( x ^{2} - 8 x + 4 )}{x ^{2}}

Simplify

\frac{1}{2} \cdot \frac{( 2 x - 8 ) x - 1 \cdot ( x ^{2} - 8 x + 4 )}{x ^{2}} : \frac{x ^{2} - 4}{2 x ^{2}}

= \frac{x ^{2} - 4}{2 x ^{2}}
