integral of 5x^2-2x+4

\int 5 x^{2} - 2 x + 4 d x

\frac{5 x ^{3}}{3} - x^{2} + 4 x + C

Solution steps

\int 5 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 5 x^{2} d x - \int 2 x d x + \int 4 d x

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

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

\int 4 d x = 4 x

= \frac{5 x ^{3}}{3} - x^{2} + 4 x

Add a constant to the solution

= \frac{5 x ^{3}}{3} - x^{2} + 4 x + C
