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

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

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

Solution steps

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

Complete the square

x (x - 2) : (x - 1)^{2} - 1

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

Apply u-substitution

: \int \frac{u ^{2} - 1}{u ^{3}} d u

= \int \frac{u ^{2} - 1}{u ^{3}} d u

Expand

\frac{u ^{2} - 1}{u ^{3}} : \frac{1}{u} - \frac{1}{u ^{3}}

= \int \frac{1}{u} - \frac{1}{u ^{3}} d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{u} d u - \int \frac{1}{u ^{3}} d u

\int \frac{1}{u} d u = ln ∣ u ∣

\int \frac{1}{u ^{3}} d u = - \frac{1}{2 u ^{2}}

= ln ∣ u ∣ - (- \frac{1}{2 u ^{2}})

Substitute back

u = x - 1

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

Simplify

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

Add a constant to the solution

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

\int_{0}^{5} x \frac{2}{95} (12 - x) d x

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

\frac{d}{d x} (\frac{4}{5} x^{10})

y = \frac{8}{x}, (16, \frac{8}{4})

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