$6 x^{2} - 5 x + 12 + 3 x^{2} + 4 x - 7$

Step 1

Add $6 x^{2}$ and $3 x^{2}$ .

$9 x^{2} - 5 x + 12 + 4 x - 7$

Step 2

Add $- 5 x$ and $4 x$ .

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

Step 3

Subtract $7$ from $12$ .

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

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