derivative of y=9x^2e^x

Solution

derivative of

y = 9 x^{2} e^{x}

Solution

9 (2 x e^{x} + e^{x} x^{2})

Solution steps

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

Take the constant out:

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

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

Apply the Product Rule:

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

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

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

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

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

= 9 (2 x e^{x} + e^{x} x^{2})
