$(- x^{2} - 4 x - 5) + (- x^{2} + 8 x + 8)$

Step 1

Remove parentheses.

$- x^{2} - 4 x - 5 - x^{2} + 8 x + 8$

Step 2

Subtract $x^{2}$ from $- x^{2}$ .

$- 2 x^{2} - 4 x - 5 + 8 x + 8$

Step 3

Add $- 4 x$ and $8 x$ .

$- 2 x^{2} + 4 x - 5 + 8$

Step 4

Add $- 5$ and $8$ .

$- 2 x^{2} + 4 x + 3$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
