integral of-x/(e^{2x)}

\int - \frac{x}{e ^{2 x}} d x

\frac{1}{2} e^{- 2 x} x + \frac{1}{4} e^{- 2 x} + C

Solution steps

\int - \frac{x}{e ^{2 x}} d x

Take the constant out:

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

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

Apply Integration By Parts

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

\int - \frac{1}{2} e^{- 2 x} d x = \frac{1}{4} e^{- 2 x}

= - (- \frac{1}{2} e^{- 2 x} x - \frac{1}{4} e^{- 2 x})

Simplify

= \frac{1}{2} e^{- 2 x} x + \frac{1}{4} e^{- 2 x}

Add a constant to the solution

= \frac{1}{2} e^{- 2 x} x + \frac{1}{4} e^{- 2 x} + C
