integral of x^2e^{13x}

\int x^{2} e^{13 x} d x

\frac{1}{13} e^{13 x} x^{2} - \frac{2}{2197} (13 e^{13 x} x - e^{13 x}) + C

Solution steps

\int x^{2} e^{13 x} d x

Apply Integration By Parts

: \frac{1}{13} e^{13 x} x^{2} - \int \frac{2}{13} e^{13 x} x d x

= \frac{1}{13} e^{13 x} x^{2} - \int \frac{2}{13} e^{13 x} x d x

\int \frac{2}{13} e^{13 x} x d x = \frac{2}{2197} (13 e^{13 x} x - e^{13 x})

= \frac{1}{13} e^{13 x} x^{2} - \frac{2}{2197} (13 e^{13 x} x - e^{13 x})

Add a constant to the solution

= \frac{1}{13} e^{13 x} x^{2} - \frac{2}{2197} (13 e^{13 x} x - e^{13 x}) + C

x \to 8 lim (\frac{1}{( x - 8 )})

\frac{\partial}{\partial y} ((2 - x) (y - 2) (3 - x - y))

\int π (2 y)^{2} d y

- \frac{50}{t ^{3}} + \frac{5}{t ^{2}}

(x^{2} ln (x))^{^{'}}
