integral of xe^{kx}

\int x e^{k x} d x

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

Solution steps

\int x e^{k x} d x

Apply Integration By Parts

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

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

= e^{k x} \frac{1}{k} x - e^{k x} \frac{1}{k ^{2}}

Add a constant to the solution

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