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

- \frac{x ^{2} + 3 x + 4}{9 e ^{x} x ^{3}}

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{x ^{2} + 3 x + 4}{9 e ^{x} x ^{3}}

= - \frac{x ^{2} + 3 x + 4}{9 e ^{x} x ^{3}}

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

\frac{\partial}{\partial s} (\frac{r + s}{t})

sin (9 ln (x))

y^{^{'}} = 3 y - 1

\frac{3 s + 3}{( s + 4 ) ^{2}}
