$(2 x^{2} + 7 x) + (- x^{2} + 10 x + 3)$

Step 1

Remove parentheses.

$2 x^{2} + 7 x - x^{2} + 10 x + 3$

Step 2

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

$x^{2} + 7 x + 10 x + 3$

Step 3

Add $7 x$ and $10 x$ .

$x^{2} + 17 x + 3$

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