integral of (7-2x)

Solution

\int (7 - 2 x) d x

Solution

7 x - x^{2} + C

Solution steps

\int 7 - 2 x 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 7 d x - \int 2 x d x

\int 7 d x = 7 x

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

= 7 x - x^{2}

Add a constant to the solution

= 7 x - x^{2} + C
