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

\frac{- x ^{2} + 3 x + 8}{7 e ^{x} x ^{3}}

Solution steps

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

Take the constant out:

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

= \frac{1}{7} \frac{d}{d x} (\frac{x - 4}{x ^{2} e ^{x}})

Apply the Quotient Rule:

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

= \frac{1}{7} \cdot \frac{\frac{d}{d x} ( x - 4 ) x ^{2} e ^{x} - \frac{d}{d x} ( x ^{2} e ^{x} ) ( x - 4 )}{( x ^{2} e ^{x} ) ^{2}}

\frac{d}{d x} (x - 4) = 1

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

= \frac{1}{7} \cdot \frac{1 \cdot x ^{2} e ^{x} - ( 2 x e ^{x} + e ^{x} x ^{2} ) ( x - 4 )}{( x ^{2} e ^{x} ) ^{2}}

Simplify

\frac{1}{7} \cdot \frac{1 \cdot x ^{2} e ^{x} - ( 2 x e ^{x} + e ^{x} x ^{2} ) ( x - 4 )}{( x ^{2} e ^{x} ) ^{2}} : \frac{- x ^{2} + 3 x + 8}{7 e ^{x} x ^{3}}

= \frac{- x ^{2} + 3 x + 8}{7 e ^{x} x ^{3}}

x \to - 1.3 lim (e^{3 x + 4})

x \to \infty lim (a x)

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

n = 3 \sum \infty \frac{1}{( n ( n - 1 ) )}

\int (y^{2} + 1) d y
