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

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

\frac{1}{14} (x^{2} - 3)^{7} + C

Solution steps

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

Apply u-substitution

: \int \frac{u ^{6}}{2} d u

= \int \frac{u ^{6}}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int u^{6} d u

Apply the Power Rule

: \frac{u ^{7}}{7}

= \frac{1}{2} \cdot \frac{u ^{7}}{7}

Substitute back

u = x^{2} - 3

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

Simplify

\frac{1}{2} \cdot \frac{( x ^{2} - 3 ) ^{7}}{7} : \frac{1}{14} (x^{2} - 3)^{7}

= \frac{1}{14} (x^{2} - 3)^{7}

Add a constant to the solution

= \frac{1}{14} (x^{2} - 3)^{7} + C

\int - 5 e^{- 5 x} d x

\int x^{2} - 9 x + 8 d x

\int \frac{7}{x ^{2} - 36} d x

\int \frac{d}{1} (cos^{4} (x)) d x

\int \frac{18}{x ^{4}} d x
