$(- 2 x^{2} - 8 x + 3) + (- 9 x^{2} + x + 3)$

Step 1

Remove parentheses.

$- 2 x^{2} - 8 x + 3 - 9 x^{2} + x + 3$

Step 2

Subtract $9 x^{2}$ from $- 2 x^{2}$ .

$- 11 x^{2} - 8 x + 3 + x + 3$

Step 3

Add $- 8 x$ and $x$ .

$- 11 x^{2} - 7 x + 3 + 3$

Step 4

Add $3$ and $3$ .

$- 11 x^{2} - 7 x + 6$

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