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

Step 1

Remove parentheses.

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

Step 2

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

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

Step 3

Add $- 4 x$ and $3 x$ .

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

Step 4

Subtract $7$ from $5$ .

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

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