integral of (4x^2)/((1-2x^3)^4)

\int \frac{4 x ^{2}}{( 1 - 2 x ^{3} ) ^{4}} d x

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

Solution steps

\int \frac{4 x ^{2}}{( 1 - 2 x ^{3} ) ^{4}} d x

Take the constant out:

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

= 4 \cdot \int \frac{x ^{2}}{( 1 - 2 x ^{3} ) ^{4}} d x

Apply u-substitution

= 4 \cdot \int \frac{1}{3 ( 1 - 2 u ) ^{4}} d u

Take the constant out:

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

= 4 \cdot \frac{1}{3} \cdot \int \frac{1}{( 1 - 2 u ) ^{4}} d u

Apply u-substitution

= 4 \cdot \frac{1}{3} \cdot \int - \frac{1}{2 v ^{4}} d v

Take the constant out:

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

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

Apply the Power Rule

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

Substitute back

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

Simplify

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

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

Add a constant to the solution

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