integral of x/((x^2+5)^2)

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

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

Solution steps

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

Apply u-substitution

: \int \frac{1}{2 u ^{2}} d u

= \int \frac{1}{2 u ^{2}} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= \frac{1}{2} (- \frac{1}{u})

Substitute back

u = x^{2} + 5

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

Simplify

\frac{1}{2} (- \frac{1}{x ^{2} + 5}) : - \frac{1}{2 ( x ^{2} + 5 )}

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

Add a constant to the solution

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

\int \frac{6 x 2 x ^{2} - 7}{5} d x

\frac{d}{d x} (\frac{3}{2 x - 1})

\frac{d}{d x} ((4 x^{2} - 13)^{- 11})

\int \frac{( x ^{2} )}{9 + x ^{6}} d x

\frac{d}{d x} (x^{- 11})
