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

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

- \frac{3}{x - 1} + C

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

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

Apply the Power Rule

= 3 (- \frac{1}{u})

Substitute back

u = x - 1

= 3 (- \frac{1}{x - 1})

Simplify

3 (- \frac{1}{x - 1}) : - \frac{3}{x - 1}

= - \frac{3}{x - 1}

Add a constant to the solution

= - \frac{3}{x - 1} + C
