integral of (2x+3)/((x+1)^2)

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

2 ln ∣ x + 1 ∣ - \frac{1}{x + 1} + C

Solution steps

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

Expand

\frac{2 x + 3}{( x + 1 ) ^{2}} : \frac{2 x}{( x + 1 ) ^{2}} + \frac{3}{( x + 1 ) ^{2}}

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

\int \frac{2 x}{( x + 1 ) ^{2}} d x = 2 (ln ∣ x + 1 ∣ + \frac{1}{x + 1})

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

= 2 (ln ∣ x + 1 ∣ + \frac{1}{x + 1}) - \frac{3}{x + 1}

Simplify

2 (ln ∣ x + 1 ∣ + \frac{1}{x + 1}) - \frac{3}{x + 1} : 2 ln ∣ x + 1 ∣ - \frac{1}{x + 1}

= 2 ln ∣ x + 1 ∣ - \frac{1}{x + 1}

Add a constant to the solution

= 2 ln ∣ x + 1 ∣ - \frac{1}{x + 1} + C

8 x^{2} + 7 y^{2} = 56

\frac{d}{d x} (\frac{x ^{2}}{2 ( 1 - x )})

\frac{\partial}{\partial y} ((x^{3} + 2 y^{2})^{3})

f (x) = \frac{cot ( x )}{1 + cot ( x )}

(1 + e^{t}) y^{^{'}} + e^{t} y = 0
