integral of (x^2+5)ln(x)

\int (x^{2} + 5) ln (x) d x

ln (x) (\frac{x ^{3}}{3} + 5 x) - \frac{1}{3} (\frac{x ^{3}}{3} + 15 x) + C

Solution steps

\int (x^{2} + 5) ln (x) d x

Apply Integration By Parts

= ln (x) (\frac{x ^{3}}{3} + 5 x) - \int \frac{1}{3} (x^{2} + 15) d x

\int \frac{1}{3} (x^{2} + 15) d x = \frac{1}{3} (\frac{x ^{3}}{3} + 15 x)

= ln (x) (\frac{x ^{3}}{3} + 5 x) - \frac{1}{3} (\frac{x ^{3}}{3} + 15 x)

Add a constant to the solution

= ln (x) (\frac{x ^{3}}{3} + 5 x) - \frac{1}{3} (\frac{x ^{3}}{3} + 15 x) + C
