derivative of (7+2x)/(5-8x)

Solution

derivative of

\frac{7 + 2 x}{5 - 8 x}

Solution

\frac{66}{( 5 - 8 x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{7 + 2 x}{5 - 8 x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 7 + 2 x ) ( 5 - 8 x ) - \frac{d}{d x} ( 5 - 8 x ) ( 7 + 2 x )}{( 5 - 8 x ) ^{2}}

\frac{d}{d x} (7 + 2 x) = 2

\frac{d}{d x} (5 - 8 x) = - 8

= \frac{2 ( 5 - 8 x ) - ( - 8 ) ( 7 + 2 x )}{( 5 - 8 x ) ^{2}}

Simplify

\frac{2 ( 5 - 8 x ) - ( - 8 ) ( 7 + 2 x )}{( 5 - 8 x ) ^{2}} : \frac{66}{( 5 - 8 x ) ^{2}}

= \frac{66}{( 5 - 8 x ) ^{2}}
