$(x^{2} - 4 x - 10) + (x^{2} - 9 x + 3)$

Step 1

Remove parentheses.

$x^{2} - 4 x - 10 + x^{2} - 9 x + 3$

Step 2

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

$2 x^{2} - 4 x - 10 - 9 x + 3$

Step 3

Subtract $9 x$ from $- 4 x$ .

$2 x^{2} - 13 x - 10 + 3$

Step 4

Add $- 10$ and $3$ .

$2 x^{2} - 13 x - 7$

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