integral of (x^5+3x^2)

\int (x^{5} + 3 x^{2}) d x

\frac{x ^{6}}{6} + x^{3} + C

Solution steps

\int x^{5} + 3 x^{2} 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^{5} d x + \int 3 x^{2} d x

\int x^{5} d x = \frac{x ^{6}}{6}

\int 3 x^{2} d x = x^{3}

= \frac{x ^{6}}{6} + x^{3}

Add a constant to the solution

= \frac{x ^{6}}{6} + x^{3} + C

\int \frac{x ^{7}}{( 4 - x ^{8} ) ^{2}} d x

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

\int x^{2} arcsin (x^{3}) d x

\int (- 7 + \frac{9}{p}) d p

\int (2 x - 6)^{2} d x
