integral of 3v(v^2+2)^2

\int 3 v (v^{2} + 2)^{2} d v

3 (\frac{v ^{6}}{6} + v^{4} + 2 v^{2}) + C

Solution steps

\int 3 v (v^{2} + 2)^{2} d v

Take the constant out:

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

= 3 \cdot \int v (v^{2} + 2)^{2} d v

Expand

v (v^{2} + 2)^{2} : v^{5} + 4 v^{3} + 4 v

= 3 \cdot \int v^{5} + 4 v^{3} + 4 v d v

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 3 (\int v^{5} d v + \int 4 v^{3} d v + \int 4 v d v)

\int v^{5} d v = \frac{v ^{6}}{6}

\int 4 v^{3} d v = v^{4}

\int 4 v d v = 2 v^{2}

= 3 (\frac{v ^{6}}{6} + v^{4} + 2 v^{2})

Add a constant to the solution

= 3 (\frac{v ^{6}}{6} + v^{4} + 2 v^{2}) + C

\int (3 x 1 - 2 x^{2}) d x

4 x + 3, x^{3} + 3

\int_{0}^{\infty} \frac{1}{e ^{x} + 1} d x

\int \frac{4 + x}{4 - x} d x
