integral of-3x^2+2x+4

\int - 3 x^{2} + 2 x + 4 d x

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

Solution steps

\int - 3 x^{2} + 2 x + 4 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 x^{2} d x + \int 2 x d x + \int 4 d x

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

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

\int 4 d x = 4 x

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

Add a constant to the solution

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

\int x \cdot sin (n \cdot x) d x

\int (\frac{- 2}{x}) d x

\int \frac{sin ^{2} ( x )}{x ^{3}} d x

\int \frac{6 x ^{3} - 6 x}{1 - 3 x ^{2} + 2 x ^{3}} d x

\int \frac{5 x}{25 - x ^{2}} d x
