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

e^{- 2 x^{2}} - 4 e^{- 2 x^{2}} x^{2}

Solution steps

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = e^{- 2 x^{2}}

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

\frac{d x}{d x} = 1

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

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

Simplify

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

= e^{- 2 x^{2}} - 4 e^{- 2 x^{2}} x^{2}
