integral of (x^2ln(x)+1)

\int (x^{2} ln (x) + 1) d x

\frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9} + x + C

Solution steps

\int x^{2} ln (x) + 1 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int x^{2} ln (x) d x + \int 1 d x

\int x^{2} ln (x) d x = \frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9}

\int 1 d x = x

= \frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9} + x

Add a constant to the solution

= \frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9} + x + C

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

\int 0.8 e^{x} d x

\int \frac{7}{( 2 x ) ^{5}} d x

\int x (x^{2} + 1)^{7} d x

\int \frac{2 x}{5 x ^{2} 16 x ^{2} - 9} d x
