$- 2 x^{2} + 8 x - 9 + 4 x + 7 x^{2} + 2$

Step 1

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

$5 x^{2} + 8 x - 9 + 4 x + 2$

Step 2

Add $8 x$ and $4 x$ .

$5 x^{2} + 12 x - 9 + 2$

Step 3

Add $- 9$ and $2$ .

$5 x^{2} + 12 x - 7$

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