integral of 4x+1

Solution

integral

4 x + 1

Solution

2 x^{2} + x + C

Solution steps

\int 4 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 4 x d x + \int 1 d x

\int 4 x d x = 2 x^{2}

\int 1 d x = x

= 2 x^{2} + x

Add a constant to the solution

= 2 x^{2} + x + C
