# Integrate xe^(7x)

### Videos

$\frac{1}{7}e^{7x}x-\frac{1}{49}e^{7x}+C_0$

## Step-by-step explanation

Problem to solve:

$\int xe^{7x}dx$
1

Use the integration by parts theorem to calculate the integral $\int x\cdot e^{7x}dx$, using the following formula

$\displaystyle\int u\cdot dv=u\cdot v-\int v \cdot du$

$\frac{1}{7}e^{7x}x-\frac{1}{49}e^{7x}+C_0$
$\int xe^{7x}dx$
