integral of (8x-10)/((2x-1)(x+1))

\int \frac{8 x - 10}{( 2 x - 1 ) ( x + 1 )} d x

- 2 ln ∣ 2 x - 1 ∣ + 6 ln ∣ x + 1 ∣ + C

Solution steps

\int \frac{8 x - 10}{( 2 x - 1 ) ( x + 1 )} d x

Take the partial fraction of

\frac{8 x - 10}{( 2 x - 1 ) ( x + 1 )} : - \frac{4}{2 x - 1} + \frac{6}{x + 1}

= \int - \frac{4}{2 x - 1} + \frac{6}{x + 1} 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{4}{2 x - 1} d x + \int \frac{6}{x + 1} d x

\int \frac{4}{2 x - 1} d x = 2 ln ∣ 2 x - 1 ∣

\int \frac{6}{x + 1} d x = 6 ln ∣ x + 1 ∣

= - 2 ln ∣ 2 x - 1 ∣ + 6 ln ∣ x + 1 ∣

Add a constant to the solution

= - 2 ln ∣ 2 x - 1 ∣ + 6 ln ∣ x + 1 ∣ + C

\int x d (e^{- x}) d x

\int x^{7} + 5 d x

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

\int sin^{3} (x) + cos^{3} (x) d x

\int \frac{4 x + 3}{x ^{2} + 1} d x
