\frac{d}{d x} (\frac{x - 2}{9 x ^{2} e ^{x}})

\frac{e ^{x} x ^{2} - ( 2 e ^{x} x + e ^{x} x ^{2} ) ( x - 2 )}{9 e ^{2 x} x ^{4}}

Solution steps

\frac{d}{d x} (\frac{x - 2}{9 x ^{2} e ^{x}})

Take the constant out:

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

= \frac{1}{9} \frac{d}{d x} (\frac{x - 2}{x ^{2} e ^{x}})

Apply the Quotient Rule:

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

= \frac{1}{9} \cdot \frac{\frac{d}{d x} ( x - 2 ) x ^{2} e ^{x} - \frac{d}{d x} ( x ^{2} e ^{x} ) ( x - 2 )}{( x ^{2} e ^{x} ) ^{2}}

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

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

= \frac{1}{9} \cdot \frac{1 \cdot x ^{2} e ^{x} - ( 2 x e ^{x} + e ^{x} x ^{2} ) ( x - 2 )}{( x ^{2} e ^{x} ) ^{2}}

Simplify

\frac{1}{9} \cdot \frac{1 \cdot x ^{2} e ^{x} - ( 2 x e ^{x} + e ^{x} x ^{2} ) ( x - 2 )}{( x ^{2} e ^{x} ) ^{2}} : \frac{e ^{x} x ^{2} - ( 2 e ^{x} x + e ^{x} x ^{2} ) ( x - 2 )}{9 e ^{2 x} x ^{4}}

= \frac{e ^{x} x ^{2} - ( 2 e ^{x} x + e ^{x} x ^{2} ) ( x - 2 )}{9 e ^{2 x} x ^{4}}

\frac{\partial}{\partial x} (8 ln (\frac{3 x y}{5 z}))

\frac{\partial}{\partial y} (e^{x + 2 y} sin (y))
