derivative of

- x e^{- x} + e^{- x}

e^{- x} x - 2 e^{- x}

Solution steps

\frac{d}{d x} (- x e^{- x} + e^{- x})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

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

= - (e^{- x} - e^{- x} x) - e^{- x}

Simplify

= e^{- x} x - 2 e^{- x}

y = e^{- x} - e^{- x} x

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

\int 2 x x - \frac{1}{x} d x

\frac{d}{d x} (ln (52 x))

\frac{d y}{d x} + 9 x y = 8 x
