integral of (4x^2)/(sqrt(1-12x^3))

\int \frac{4 x ^{2}}{1 - 12 x ^{3}} d x

- \frac{2}{9} 1 - 12 x^{3} + C

Solution steps

\int \frac{4 x ^{2}}{1 - 12 x ^{3}} 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 - 12 x ^{3}} d x

Apply u-substitution

= 4 \cdot \int - \frac{1}{36 u} d u

Take the constant out:

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

= 4 (- \frac{1}{36} \cdot \int \frac{1}{u} d u)

Apply the Power Rule

= 4 (- \frac{1}{36} \cdot 2 u^{\frac{1}{2}})

Substitute back

u = 1 - 12 x^{3}

= 4 (- \frac{1}{36} \cdot 2 (1 - 12 x^{3})^{\frac{1}{2}})

Simplify

4 (- \frac{1}{36} \cdot 2 (1 - 12 x^{3})^{\frac{1}{2}}) : - \frac{2}{9} 1 - 12 x^{3}

= - \frac{2}{9} 1 - 12 x^{3}

Add a constant to the solution

= - \frac{2}{9} 1 - 12 x^{3} + C
