integral of 5/((3x-1)^2)

\int \frac{5}{( 3 x - 1 ) ^{2}} d x

- \frac{5}{3 ( 3 x - 1 )} + C

Solution steps

\int \frac{5}{( 3 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{1}{( 3 x - 1 ) ^{2}} d x

Apply u-substitution

= 5 \cdot \int \frac{1}{3 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}{3} \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

= 5 \cdot \frac{1}{3} (- \frac{1}{u})

Substitute back

u = 3 x - 1

= 5 \cdot \frac{1}{3} (- \frac{1}{3 x - 1})

Simplify

5 \cdot \frac{1}{3} (- \frac{1}{3 x - 1}) : - \frac{5}{3 ( 3 x - 1 )}

= - \frac{5}{3 ( 3 x - 1 )}

Add a constant to the solution

= - \frac{5}{3 ( 3 x - 1 )} + C
