integral of 7x-2

Solution

\int 7 x - 2 d x

Solution

\frac{7 x ^{2}}{2} - 2 x + C

Solution steps

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

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 2 d x = 2 x

= \frac{7 x ^{2}}{2} - 2 x

Add a constant to the solution

= \frac{7 x ^{2}}{2} - 2 x + C
