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

Step 1

Subtract $7 x^{2}$ from $2 x^{2}$ .

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

Step 2

Add $6 x$ and $3 x$ .

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

Step 3

Add $- 5$ and $4$ .

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

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