$\int_{- 4}^{- 2} - x + | - 3 x - 9 | d x$

Step 1

Split the single integral into multiple integrals.

$\int_{- 4}^{- 2} - x d x + \int_{- 4}^{- 2} | - 3 x - 9 | d x$

Step 2

Since $- 1$ is constant with respect to $x$ , move $- 1$ out of the integral.

$- \int_{- 4}^{- 2} x d x + \int_{- 4}^{- 2} | - 3 x - 9 | d x$

Step 3

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

$- (\frac{1}{2} x^{2}]_{- 4}^{- 2}) + \int_{- 4}^{- 2} | - 3 x - 9 | d x$

Step 4

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

$- (\frac{x^{2}}{2}]_{- 4}^{- 2}) + \int_{- 4}^{- 2} | - 3 x - 9 | d x$

Step 5

Split up the integral depending on where $- 3 x - 9$ is positive and negative.

Step 13

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

$- (\frac{x^{2}}{2}]_{- 4}^{- 2}) - 3 (\frac{x^{2}}{2}]_{- 4}^{- 3}) + - 9 x]_{- 4}^{- 3} + 3 (\frac{1}{2} x^{2}]_{- 3}^{- 2}) + \int_{- 3}^{- 2} 9 d x$

Step 16.6.37.2

Subtract $9$ from $4$ .

$\frac{15}{2} + 3 (\frac{- 5}{2}) + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.38

Move the negative in front of the fraction.

$\frac{15}{2} + 3 (- \frac{5}{2}) + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.39

Multiply $- 1$ by $3$ .

$\frac{15}{2} - 3 (\frac{5}{2}) + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.40

Combine $- 3$ and $\frac{5}{2}$ .

$\frac{15}{2} + \frac{- 3 \cdot 5}{2} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.41

Multiply $- 3$ by $5$ .

$\frac{15}{2} + \frac{- 15}{2} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.42

Move the negative in front of the fraction.

$\frac{15}{2} - \frac{15}{2} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.43

Combine the numerators over the common denominator.

$\frac{15 - 15}{2} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.44

Subtract $15$ from $15$ .

$\frac{0}{2} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.45

Cancel the common factor of $0$ and $2$ .

Step 16.6.45.2.1

Factor $2$ out of $2$ .

$\frac{2 \cdot 0}{2 \cdot 1} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.45.2.2

Cancel the common factor.

$\frac{2 \cdot 0}{2 \cdot 1} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.45.2.3

Rewrite the expression.

$\frac{0}{1} + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.45.2.4

Divide $0$ by $1$ .

$0 + (9 \cdot - 2) - 9 \cdot - 3$

Step 16.6.46

Multiply $9$ by $- 2$ .

$0 - 18 - 9 \cdot - 3$

Step 16.6.47

Multiply $- 9$ by $- 3$ .

$0 - 18 + 27$

Step 16.6.48

Add $- 18$ and $27$ .

$0 + 9$

Step 16.6.49

Add $0$ and $9$ .

$9$
