integral of-2x+1

Solution

\int - 2 x + 1 d x

Solution

- x^{2} + x + C

Solution steps

\int - 2 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 2 x d x + \int 1 d x

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

\int 1 d x = x

= - x^{2} + x

Add a constant to the solution

= - x^{2} + x + C
