$8 x^{2} - 7 x + 2 + (3 x^{2} - 9 x - 6)$

Step 1

Remove parentheses.

$8 x^{2} - 7 x + 2 + 3 x^{2} - 9 x - 6$

Step 2

Add $8 x^{2}$ and $3 x^{2}$ .

$11 x^{2} - 7 x + 2 - 9 x - 6$

Step 3

Subtract $9 x$ from $- 7 x$ .

$11 x^{2} - 16 x + 2 - 6$

Step 4

Subtract $6$ from $2$ .

$11 x^{2} - 16 x - 4$
