$\int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} (x + 2) - (x^{2} + 5 x - 4) d x$

Step 1

Split the single integral into multiple integrals.

$\int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} x d x + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} 2 d x + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (x^{2} + 5 x - 4) d x$

Step 2

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

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} 2 d x + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (x^{2} + 5 x - 4) d x$

Step 3

Apply the constant rule.

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 2 x]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (x^{2} + 5 x - 4) d x$

Step 4

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

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 2 x]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} x^{2} + 5 x - 4 d x$

Step 6

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

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 2 x]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (\frac{1}{3} x^{3}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} 5 x d x + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - 4 d x)$

Step 8

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

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 2 x]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (\frac{x^{3}}{3}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 5 \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} x d x + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - 4 d x)$

Step 9

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

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 2 x]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (\frac{x^{3}}{3}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 5 (\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}}) + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - 4 d x)$

Step 10

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

$\frac{1}{2} x^{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 2 x]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - (\frac{x^{3}}{3}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} + 5 (\frac{x^{2}}{2}]_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}}) + \int_{- 2 - \sqrt{10}}^{- 2 + \sqrt{10}} - 4 d x)$
