integral of (12x)/((3x^2-9)^5)

\int \frac{12 x}{( 3 x ^{2} - 9 ) ^{5}} d x

- \frac{1}{2 ( 3 x ^{2} - 9 ) ^{4}} + C

Solution steps

\int \frac{12 x}{( 3 x ^{2} - 9 ) ^{5}} d x

Take the constant out:

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

= 12 \cdot \int \frac{x}{( 3 x ^{2} - 9 ) ^{5}} d x

Apply u-substitution

= 12 \cdot \int \frac{1}{2 ( 3 u - 9 ) ^{5}} d u

Take the constant out:

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

= 12 \cdot \frac{1}{2} \cdot \int \frac{1}{( 3 u - 9 ) ^{5}} d u

Apply u-substitution

= 12 \cdot \frac{1}{2} \cdot \int \frac{1}{3 v ^{5}} d v

Take the constant out:

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

= 12 \cdot \frac{1}{2} \cdot \frac{1}{3} \cdot \int \frac{1}{v ^{5}} d v

Apply the Power Rule

= 12 \cdot \frac{1}{2} \cdot \frac{1}{3} (- \frac{1}{4 v ^{4}})

Substitute back

= 12 \cdot \frac{1}{2} \cdot \frac{1}{3} (- \frac{1}{4 ( 3 x ^{2} - 9 ) ^{4}})

Simplify

12 \cdot \frac{1}{2} \cdot \frac{1}{3} (- \frac{1}{4 ( 3 x ^{2} - 9 ) ^{4}}) : - \frac{1}{2 ( 3 x ^{2} - 9 ) ^{4}}

= - \frac{1}{2 ( 3 x ^{2} - 9 ) ^{4}}

Add a constant to the solution

= - \frac{1}{2 ( 3 x ^{2} - 9 ) ^{4}} + C
