integral of (x^2+5)^32x

\int (x^{2} + 5)^{3} 2 x d x

\frac{1}{4} (x^{2} + 5)^{4} + C

Solution steps

\int (x^{2} + 5)^{3} \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)^{3} x d x

Apply u-substitution

: \int \frac{u ^{3}}{2} d u

= 2 \cdot \int \frac{u ^{3}}{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^{3} d u

Apply the Power Rule

: \frac{u ^{4}}{4}

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

Substitute back

u = x^{2} + 5

= 2 \cdot \frac{1}{2} \cdot \frac{( x ^{2} + 5 ) ^{4}}{4}

Simplify

2 \cdot \frac{1}{2} \cdot \frac{( x ^{2} + 5 ) ^{4}}{4} : \frac{1}{4} (x^{2} + 5)^{4}

= \frac{1}{4} (x^{2} + 5)^{4}

Add a constant to the solution

= \frac{1}{4} (x^{2} + 5)^{4} + C

\int - \frac{t ^{2}}{t ^{2} + 4 t + 3} d t

\int \frac{3 x + 1}{x ^{2} + 2 x + 2} d x

\int \frac{2 x ^{3}}{4 + x ^{8}} d x

\int \frac{x ^{4} - 8 x ^{2} + 5 x}{x ^{2}} d x

\int 9 + e^{2 x} - \frac{5}{x ^{3}} d x
