$(5 x + 2) + (x^{2} - 9) + (x^{2} - 7 x + 12)$

Step 1

Remove parentheses.

$5 x + 2 + x^{2} - 9 + x^{2} - 7 x + 12$

Step 2

Subtract $7 x$ from $5 x$ .

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

Step 3

Subtract $9$ from $2$ .

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

Step 4

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

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

Step 5

Step 5.1

Add $- 7$ and $12$ .

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

Step 5.2

Reorder $- 2 x$ and $2 x^{2}$ .

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

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

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