integral of 5x^2+7x-2

\int 5 x^{2} + 7 x - 2 d x

\frac{5 x ^{3}}{3} + \frac{7 x ^{2}}{2} - 2 x + C

Solution steps

\int 5 x^{2} + 7 x - 2 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 7 x d x - \int 2 d x

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

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 2 d x = 2 x

= \frac{5 x ^{3}}{3} + \frac{7 x ^{2}}{2} - 2 x

Add a constant to the solution

= \frac{5 x ^{3}}{3} + \frac{7 x ^{2}}{2} - 2 x + C

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

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

\int 81 x^{2} + 35 d x

\int (x + 4) (x - 7) d x

\int 15 x^{3} cos (5 x^{4} + 11) d x
