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

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

- \frac{x ^{2}}{2 ( x + 3 ) ^{2}} + ln ∣ x + 3 ∣ + \frac{3}{x + 3} + C

Solution steps

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

Apply Integration By Parts

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

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

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

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

Simplify

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

Add a constant to the solution

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

x \to 0 - lim ([x ln ∣ x ∣ - x])

\frac{\partial}{\partial y} (x^{ey})

y = tan^{2} (7 x)

\frac{d}{d x} (x 800 - x)

\int \frac{( x - 9 )}{( x + 5 ) ( x - 2 )} d x
