$\int 3 x^{5} - 8 x^{3} + 2 d x$

Step 1

Split the single integral into multiple integrals.

$\int 3 x^{5} d x + \int - 8 x^{3} d x + \int 2 d x$

Step 2

Since $3$ is constant with respect to $x$ , move $3$ out of the integral.

$3 \int x^{5} d x + \int - 8 x^{3} d x + \int 2 d x$

Step 3

By the Power Rule, the integral of $x^{5}$ with respect to $x$ is $\frac{1}{6} x^{6}$ .

$3 (\frac{1}{6} x^{6} + C) + \int - 8 x^{3} d x + \int 2 d x$

Step 4

Since $- 8$ is constant with respect to $x$ , move $- 8$ out of the integral.

$3 (\frac{1}{6} x^{6} + C) - 8 \int x^{3} d x + \int 2 d x$

Step 5

By the Power Rule, the integral of $x^{3}$ with respect to $x$ is $\frac{1}{4} x^{4}$ .

$3 (\frac{1}{6} x^{6} + C) - 8 (\frac{1}{4} x^{4} + C) + \int 2 d x$

Step 6

Apply the constant rule.

$3 (\frac{1}{6} x^{6} + C) - 8 (\frac{1}{4} x^{4} + C) + 2 x + C$
