integral of (x^2-5)/((x+1)^3)

\int \frac{x ^{2} - 5}{( x + 1 ) ^{3}} d x

- \frac{x ^{2} - 5}{2 ( x + 1 ) ^{2}} + ln ∣ x + 1 ∣ + \frac{1}{x + 1} + C

Solution steps

\int \frac{x ^{2} - 5}{( x + 1 ) ^{3}} d x

Apply Integration By Parts

= - \frac{x ^{2} - 5}{2 ( x + 1 ) ^{2}} - \int - \frac{x}{( x + 1 ) ^{2}} d x

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

= - \frac{x ^{2} - 5}{2 ( x + 1 ) ^{2}} - (- ln ∣ x + 1 ∣ - \frac{1}{x + 1})

Simplify

= - \frac{x ^{2} - 5}{2 ( x + 1 ) ^{2}} + ln ∣ x + 1 ∣ + \frac{1}{x + 1}

Add a constant to the solution

= - \frac{x ^{2} - 5}{2 ( x + 1 ) ^{2}} + ln ∣ x + 1 ∣ + \frac{1}{x + 1} + C

\int_{0}^{π} 20 sin^{4} (x) d x

\int 3 x cos (3 x) d x

y^{^{'}} - 2 y = 3 e^{2 t}

\frac{d}{d x} (x^{2} + 15)

x \to - 2 lim (- 7)
