integral of 1-3x

Solution

\int 1 - 3 x d x

Solution

x - \frac{3 x ^{2}}{2} + C

Solution steps

\int 1 - 3 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 1 d x - \int 3 x d x

\int 1 d x = x

\int 3 x d x = \frac{3 x ^{2}}{2}

= x - \frac{3 x ^{2}}{2}

Add a constant to the solution

= x - \frac{3 x ^{2}}{2} + C
