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

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

\frac{1}{10} (x^{2} - 2)^{5} + C

Solution steps

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

Apply u-substitution

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

Apply the Power Rule

= \frac{1}{2} \cdot \frac{u ^{5}}{5}

Substitute back

u = x^{2} - 2

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

Simplify

\frac{1}{2} \cdot \frac{( x ^{2} - 2 ) ^{5}}{5} : \frac{1}{10} (x^{2} - 2)^{5}

= \frac{1}{10} (x^{2} - 2)^{5}

Add a constant to the solution

= \frac{1}{10} (x^{2} - 2)^{5} + C
