integral of (3x-7x^2)/x

\int \frac{3 x - 7 x ^{2}}{x} d x

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

Solution steps

\int \frac{3 x - 7 x ^{2}}{x} d x

Expand

\frac{3 x - 7 x ^{2}}{x} : \frac{3 x}{x} - \frac{7 x ^{2}}{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 \frac{3 x}{x} d x - \int \frac{7 x ^{2}}{x} d x

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

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

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

Add a constant to the solution

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

\int ∣ x ∣ - 1 d x

\int \frac{1 - x}{1 + x} \cdot \frac{1}{x} d x

\int 9 x^{2} e^{x^{3}} d x

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

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