integral of (3-8x)

Solution

\int (3 - 8 x) d x

Solution

3 x - 4 x^{2} + C

Solution steps

\int 3 - 8 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 3 d x - \int 8 x d x

\int 3 d x = 3 x

\int 8 x d x = 4 x^{2}

= 3 x - 4 x^{2}

Add a constant to the solution

= 3 x - 4 x^{2} + C
