$7 x^{2} - 6 x - 1 + (2 x^{2} - 3 x - 5)$

Step 1

Remove parentheses.

$7 x^{2} - 6 x - 1 + 2 x^{2} - 3 x - 5$

Step 2

Add $7 x^{2}$ and $2 x^{2}$ .

$9 x^{2} - 6 x - 1 - 3 x - 5$

Step 3

Subtract $3 x$ from $- 6 x$ .

$9 x^{2} - 9 x - 1 - 5$

Step 4

Subtract $5$ from $- 1$ .

$9 x^{2} - 9 x - 6$

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