integral of 6x(3x^2-2)^4

\int 6 x (3 x^{2} - 2)^{4} d x

\frac{1}{5} (3 x^{2} - 2)^{5} + C

Solution steps

\int 6 x (3 x^{2} - 2)^{4} d x

Take the constant out:

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

= 6 \cdot \int x (3 x^{2} - 2)^{4} d x

Apply u-substitution

= 6 \cdot \int \frac{u ^{4}}{6} d u

Take the constant out:

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

= 6 \cdot \frac{1}{6} \cdot \int u^{4} d u

Apply the Power Rule

= 6 \cdot \frac{1}{6} \cdot \frac{u ^{5}}{5}

Substitute back

u = 3 x^{2} - 2

= 6 \cdot \frac{1}{6} \cdot \frac{( 3 x ^{2} - 2 ) ^{5}}{5}

Simplify

6 \cdot \frac{1}{6} \cdot \frac{( 3 x ^{2} - 2 ) ^{5}}{5} : \frac{1}{5} (3 x^{2} - 2)^{5}

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

Add a constant to the solution

= \frac{1}{5} (3 x^{2} - 2)^{5} + C
