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

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

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

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

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

= 5 \cdot \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

= 5 \cdot \frac{1}{2} \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= 5 \cdot \frac{1}{2} (- \frac{1}{u})

Substitute back

u = x^{2} + 5

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

Simplify

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

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

Add a constant to the solution

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

\frac{d}{d x} (- cos (\frac{x}{2}))

\frac{- 6 x}{( x ^{2} + 1 )}

\frac{d}{d x} (\frac{sin ^{2} ( x )}{1 + cos ^{2} ( x )})

\int \frac{1}{( 4 x + 5 ) ^{2}} d x

\frac{8 x}{( x + 1 ) ^{2}}
