integral of (2x-7)

Solution

\int (2 x - 7) d x

Solution

x^{2} - 7 x + C

Solution steps

\int 2 x - 7 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 7 d x

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

\int 7 d x = 7 x

= x^{2} - 7 x

Add a constant to the solution

= x^{2} - 7 x + C
