integral of (3x^2+2)

Solution

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

Solution

x^{3} + 2 x + C

Solution steps

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

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

\int 2 d x = 2 x

= x^{3} + 2 x

Add a constant to the solution

= x^{3} + 2 x + C
