derivative of

x^{2} e^{- 7 x}

2 e^{- 7 x} x - 7 e^{- 7 x} x^{2}

Solution steps

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

Apply the Product Rule:

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

f = x^{2}, g = e^{- 7 x}

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

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

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

= 2 x e^{- 7 x} + (- 7 e^{- 7 x}) x^{2}

Simplify

= 2 e^{- 7 x} x - 7 e^{- 7 x} x^{2}
