integral of (11x+8)/(10x^2+5x)

\int \frac{11 x + 8}{10 x ^{2} + 5 x} d x

\frac{11}{10} ln ∣ 2 x + 1 ∣ - \frac{8}{5} (ln ∣ 4 x + 2 ∣ - ln (4 ∣ x ∣)) + C

Solution steps

\int \frac{11 x + 8}{10 x ^{2} + 5 x} d x

Expand

\frac{11 x + 8}{10 x ^{2} + 5 x} : \frac{11 x}{10 x ^{2} + 5 x} + \frac{8}{10 x ^{2} + 5 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{11 x}{10 x ^{2} + 5 x} d x + \int \frac{8}{10 x ^{2} + 5 x} d x

\int \frac{11 x}{10 x ^{2} + 5 x} d x = \frac{11}{10} ln ∣ 2 x + 1 ∣

\int \frac{8}{10 x ^{2} + 5 x} d x = - \frac{8}{5} (ln ∣ 4 x + 2 ∣ - ln (4 ∣ x ∣))

= \frac{11}{10} ln ∣ 2 x + 1 ∣ - \frac{8}{5} (ln ∣ 4 x + 2 ∣ - ln (4 ∣ x ∣))

Add a constant to the solution

= \frac{11}{10} ln ∣ 2 x + 1 ∣ - \frac{8}{5} (ln ∣ 4 x + 2 ∣ - ln (4 ∣ x ∣)) + C

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

\int 5 x^{4} e^{- 3 x} d x

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

\int - sin (x) + 1 d x

\int 3 u^{2} d u
