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

Step 1

Remove parentheses.

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

Step 2

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

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

Step 3

Add $- 3 x$ and $7 x$ .

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

Step 4

Subtract $2$ from $- 3$ .

$3 x^{2} + 4 x - 5$

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