\frac{d}{d x} (\frac{4 x ^{2}}{( 7 - 5 x ) ^{3}})

\frac{4 x ( 5 x + 14 )}{( 7 - 5 x ) ^{4}}

Solution steps

\frac{d}{d x} (\frac{4 x ^{2}}{( 7 - 5 x ) ^{3}})

Take the constant out:

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

= 4 \frac{d}{d x} (\frac{x ^{2}}{( 7 - 5 x ) ^{3}})

Apply the Quotient Rule:

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

= 4 \cdot \frac{\frac{d}{d x} ( x ^{2} ) ( 7 - 5 x ) ^{3} - \frac{d}{d x} ( ( 7 - 5 x ) ^{3} ) x ^{2}}{( ( 7 - 5 x ) ^{3} ) ^{2}}

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

\frac{d}{d x} ((7 - 5 x)^{3}) = - 15 (7 - 5 x)^{2}

= 4 \cdot \frac{2 x ( 7 - 5 x ) ^{3} - ( - 15 ( 7 - 5 x ) ^{2} ) x ^{2}}{( ( 7 - 5 x ) ^{3} ) ^{2}}

Simplify

4 \cdot \frac{2 x ( 7 - 5 x ) ^{3} - ( - 15 ( 7 - 5 x ) ^{2} ) x ^{2}}{( ( 7 - 5 x ) ^{3} ) ^{2}} : \frac{4 x ( 5 x + 14 )}{( 7 - 5 x ) ^{4}}

= \frac{4 x ( 5 x + 14 )}{( 7 - 5 x ) ^{4}}

\int \frac{e ^{x}}{4 + e ^{2 x}} d x

\int t (t^{4} + t - 5) d t

\frac{\partial}{\partial x} (2 y - \frac{3}{y ^{2}} + x)

(x^{6} - 5) x

\frac{d}{d x} (\frac{cos ( x )}{x + 1})
