integral of 2x+3

Solution

\int 2 x + 3 d x

Solution

x^{2} + 3 x + C

Solution steps

\int 2 x + 3 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 3 d x

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

\int 3 d x = 3 x

= x^{2} + 3 x

Add a constant to the solution

= x^{2} + 3 x + C
