integral of e^{3x}(2x+3)

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

\frac{2}{3} e^{3 x} x + \frac{7}{9} e^{3 x} + C

Solution steps

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

Apply Integration By Parts

= \frac{2}{3} e^{3 x} x + e^{3 x} - \int \frac{2}{3} e^{3 x} d x

\int \frac{2}{3} e^{3 x} d x = \frac{2}{9} e^{3 x}

= \frac{2}{3} e^{3 x} x + e^{3 x} - \frac{2}{9} e^{3 x}

Add similar elements:

e^{3 x} - \frac{2}{9} e^{3 x} = \frac{7}{9} e^{3 x}

= \frac{2}{3} e^{3 x} x + \frac{7}{9} e^{3 x}

Add a constant to the solution

= \frac{2}{3} e^{3 x} x + \frac{7}{9} e^{3 x} + C
