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

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

7 ln ∣ x ∣ - 3 e^{x} + C

Solution steps

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

Expand

\frac{7 - 3 x e ^{x}}{x} : \frac{7}{x} - 3 e^{x}

= \int \frac{7}{x} - 3 e^{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 \frac{7}{x} d x - \int 3 e^{x} d x

\int \frac{7}{x} d x = 7 ln ∣ x ∣

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

= 7 ln ∣ x ∣ - 3 e^{x}

Add a constant to the solution

= 7 ln ∣ x ∣ - 3 e^{x} + C

\int 5 x^{2} - 8 x + 4 d x

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

\int \frac{3}{5 y ^{2} + 4} d y

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