integral of (-2x^2+4x)

\int (- 2 x^{2} + 4 x) d x

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

Solution steps

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

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

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

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

Add a constant to the solution

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

\int \frac{cos ( 5 x )}{5} d x

\int k (1 - y) y^{n} d y

\int 2 x y - 1 d x

\int x (x - 3)^{2} (x + 1) d x

\int x (x^{\frac{3}{2}} - 10)^{4} d x
