integral of 2x^2e^{5x}

\int 2 x^{2} e^{5 x} d x

2 (\frac{1}{5} e^{5 x} x^{2} - \frac{2}{125} (5 e^{5 x} x - e^{5 x})) + C

Solution steps

\int 2 x^{2} e^{5 x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int x^{2} e^{5 x} d x

Apply Integration By Parts

: \frac{1}{5} e^{5 x} x^{2} - \int \frac{2}{5} e^{5 x} x d x

= 2 (\frac{1}{5} e^{5 x} x^{2} - \int \frac{2}{5} e^{5 x} x d x)

\int \frac{2}{5} e^{5 x} x d x = \frac{2}{125} (5 e^{5 x} x - e^{5 x})

= 2 (\frac{1}{5} e^{5 x} x^{2} - \frac{2}{125} (5 e^{5 x} x - e^{5 x}))

Add a constant to the solution

= 2 (\frac{1}{5} e^{5 x} x^{2} - \frac{2}{125} (5 e^{5 x} x - e^{5 x})) + C

\int \frac{e ^{- x} - e ^{- a x}}{x} d x

\int x + e^{- y} d x

\int (x^{\frac{3}{2}} + 3)^{6} x d x

\int 7 x x^{2} + 6 d x

\int x (1 + x - x^{2}) d x
