integral of (5x)/((x-1)^2)

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

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

Solution steps

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

Apply u-substitution

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

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

Expand

\frac{u + 1}{u ^{2}} : \frac{1}{u} + \frac{1}{u ^{2}}

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

= 5 (\int \frac{1}{u} d u + \int \frac{1}{u ^{2}} d u)

\int \frac{1}{u} d u = ln ∣ u ∣

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

= 5 (ln ∣ u ∣ - \frac{1}{u})

Substitute back

u = x - 1

= 5 (ln ∣ x - 1 ∣ - \frac{1}{x - 1})

Add a constant to the solution

= 5 (ln ∣ x - 1 ∣ - \frac{1}{x - 1}) + C

\int x^{\frac{1}{3}} + 8 d x

\int \frac{y}{y ^{2} + z ^{2}} d y

\int sin (π x) - 3 sin (3 x) d x

\int \frac{1}{7 x - 4} d x

\int \frac{1}{1 - 1 - x ^{2}} d x
