integral of 5x-x^2-x

Solution

\int 5 x - x^{2} - x d x

Solution

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

Solution steps

\int 5 x - x^{2} - x d x

Simplify

= \int - x^{2} + 4 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 x^{2} d x + \int 4 x d x

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

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

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

Add a constant to the solution

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