integral of (2x^2)/(sqrt(7-6x^3))

\int \frac{2 x ^{2}}{7 - 6 x ^{3}} d x

- \frac{2}{9} 7 - 6 x^{3} + C

Solution steps

\int \frac{2 x ^{2}}{7 - 6 x ^{3}} d x

Take the constant out:

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

= 2 \cdot \int \frac{x ^{2}}{7 - 6 x ^{3}} d x

Apply u-substitution

: \int - \frac{1}{18 u} d u

= 2 \cdot \int - \frac{1}{18 u} d u

Take the constant out:

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

= 2 (- \frac{1}{18} \cdot \int \frac{1}{u} d u)

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= 2 (- \frac{1}{18} \cdot 2 u^{\frac{1}{2}})

Substitute back

u = 7 - 6 x^{3}

= 2 (- \frac{1}{18} \cdot 2 (7 - 6 x^{3})^{\frac{1}{2}})

Simplify

2 (- \frac{1}{18} \cdot 2 (7 - 6 x^{3})^{\frac{1}{2}}) : - \frac{2}{9} 7 - 6 x^{3}

= - \frac{2}{9} 7 - 6 x^{3}

Add a constant to the solution

= - \frac{2}{9} 7 - 6 x^{3} + C

\int x^{2} sin^{2} (x^{3}) d x

\int (4 - 3 x)^{6} d x

\int t cos (3 t) d t

\int \frac{4 w + 3}{4 w ^{2} + 6 w - 1} d w

\int (2 x + 1) (3 - x) d x
