\frac{d}{d x} (\frac{- 6 x}{2 x - 1})

- \frac{6 ( x - 1 )}{( 2 x - 1 ) 2 x - 1}

Solution steps

\frac{d}{d x} (\frac{- 6 x}{2 x - 1})

Simplify

\frac{- 6 x}{2 x - 1} : - \frac{6 x}{2 x - 1}

= \frac{d}{d x} (- \frac{6 x}{2 x - 1})

Take the constant out:

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

= - 6 \frac{d}{d x} (\frac{x}{2 x - 1})

Apply the Quotient Rule:

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

= - 6 \cdot \frac{\frac{d x}{d x} 2 x - 1 - \frac{d}{d x} ( 2 x - 1 ) x}{( 2 x - 1 ) ^{2}}

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

\frac{d}{d x} (2 x - 1) = \frac{1}{2 x - 1}

= - 6 \cdot \frac{1 \cdot 2 x - 1 - \frac{1}{2 x - 1} x}{( 2 x - 1 ) ^{2}}

Simplify

- 6 \cdot \frac{1 \cdot 2 x - 1 - \frac{1}{2 x - 1} x}{( 2 x - 1 ) ^{2}} : - \frac{6 ( x - 1 )}{( 2 x - 1 ) 2 x - 1}

= - \frac{6 ( x - 1 )}{( 2 x - 1 ) 2 x - 1}
