$\int (- 5 x^{- 3} - 6) d x$

Step 1

Remove parentheses.

$\int - 5 x^{- 3} - 6 d x$

Step 2

Split the single integral into multiple integrals.

$\int - 5 x^{- 3} d x + \int - 6 d x$

Step 3

Since $- 5$ is constant with respect to $x$ , move $- 5$ out of the integral.

$- 5 \int x^{- 3} d x + \int - 6 d x$

Step 4

By the Power Rule, the integral of $x^{- 3}$ with respect to $x$ is $- \frac{1}{2} x^{- 2}$ .

$- 5 (- \frac{1}{2} x^{- 2} + C) + \int - 6 d x$

Step 5

Simplify.

Step 5.1

Combine $x^{- 2}$ and $\frac{1}{2}$ .

$- 5 (- \frac{x^{- 2}}{2} + C) + \int - 6 d x$

Step 5.2

Move $x^{- 2}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$- 5 (- \frac{1}{2 x^{2}} + C) + \int - 6 d x$

Step 6

Apply the constant rule.

$- 5 (- \frac{1}{2 x^{2}} + C) - 6 x + C$

Step 7

Simplify.

$\frac{5}{2 x^{2}} - 6 x + C$
