integral of 2x+x^2

Solution

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

Solution

x^{2} + \frac{x ^{3}}{3} + C

Solution steps

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

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

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

= x^{2} + \frac{x ^{3}}{3}

Add a constant to the solution

= x^{2} + \frac{x ^{3}}{3} + C
