integral of 5x^3(x-5)^{-4}

\int 5 x^{3} (x - 5)^{- 4} d x

5 (- \frac{x ^{3}}{3 ( x - 5 ) ^{3}} + ln ∣ x - 5 ∣ - \frac{10}{x - 5} - \frac{25}{2 ( x - 5 ) ^{2}}) + C

Solution steps

\int 5 x^{3} (x - 5)^{- 4} d x

Take the constant out:

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

= 5 \cdot \int x^{3} (x - 5)^{- 4} d x

Simplify

x^{3} (x - 5)^{- 4} : \frac{x ^{3}}{( x - 5 ) ^{4}}

= 5 \cdot \int \frac{x ^{3}}{( x - 5 ) ^{4}} d x

Apply Integration By Parts

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

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

\int - \frac{x ^{2}}{( x - 5 ) ^{3}} d x = - ln ∣ x - 5 ∣ + \frac{10}{x - 5} + \frac{25}{2 ( x - 5 ) ^{2}}

= 5 (- \frac{x ^{3}}{3 ( x - 5 ) ^{3}} - (- ln ∣ x - 5 ∣ + \frac{10}{x - 5} + \frac{25}{2 ( x - 5 ) ^{2}}))

Simplify

= 5 (- \frac{x ^{3}}{3 ( x - 5 ) ^{3}} + ln ∣ x - 5 ∣ - \frac{10}{x - 5} - \frac{25}{2 ( x - 5 ) ^{2}})

Add a constant to the solution

= 5 (- \frac{x ^{3}}{3 ( x - 5 ) ^{3}} + ln ∣ x - 5 ∣ - \frac{10}{x - 5} - \frac{25}{2 ( x - 5 ) ^{2}}) + C

\frac{s + 2}{( s - 1 ) ( s + 6 )}

2 x, x^{2} - 4 x

y^{^{'}} + 2 y = x^{2} + 2 x

\int_{0}^{1} \frac{2 x}{( x ^{2} + 2 ) ^{3}} d x

\frac{\partial}{\partial y} (tan (4 + 2 x^{2} y^{3} z^{2}))
