integral of x^2e^{22x}

\int x^{2} e^{22 x} d x

\frac{1}{22} e^{22 x} x^{2} - \frac{1}{5324} (22 e^{22 x} x - e^{22 x}) + C

Solution steps

\int x^{2} e^{22 x} d x

Apply Integration By Parts

: \frac{1}{22} e^{22 x} x^{2} - \int \frac{1}{11} e^{22 x} x d x

= \frac{1}{22} e^{22 x} x^{2} - \int \frac{1}{11} e^{22 x} x d x

\int \frac{1}{11} e^{22 x} x d x = \frac{1}{5324} (22 e^{22 x} x - e^{22 x})

= \frac{1}{22} e^{22 x} x^{2} - \frac{1}{5324} (22 e^{22 x} x - e^{22 x})

Add a constant to the solution

= \frac{1}{22} e^{22 x} x^{2} - \frac{1}{5324} (22 e^{22 x} x - e^{22 x}) + C

y = \frac{x ^{3} + 1}{x ^{2} - 1}

f (x) = \frac{x ^{2}}{x ^{2} + 2}

\int x^{3} e^{- a x^{2}} d x

\int 54

(x)^{5 x}
