derivative of (2x-1/(x-1))

Solution

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

Solution

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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