integral of (x^2-5)^4(2x)

\int (x^{2} - 5)^{4} (2 x) d x

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

Solution steps

\int (x^{2} - 5)^{4} \cdot 2 x d x

Take the constant out:

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

= 2 \cdot \int (x^{2} - 5)^{4} x d x

Apply u-substitution

: \int \frac{u ^{4}}{2} d u

= 2 \cdot \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

= 2 \cdot \frac{1}{2} \cdot \int u^{4} d u

Apply the Power Rule

: \frac{u ^{5}}{5}

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

Substitute back

u = x^{2} - 5

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

Simplify

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

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

Add a constant to the solution

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

\int (2 e^{x} + sec (x) tan (x) - x) d x

\int tan (4 t) d t

\int 3 x^{2} - π x d x

\int \frac{5}{2} x^{2} (x^{3} - 7)^{4} d x

\int \frac{5 sin ( x )}{x} d x
