$(x^{2} - 5 x + 6) + (3 x^{2} - 8 x - 2)$

Step 1

Remove parentheses.

$x^{2} - 5 x + 6 + 3 x^{2} - 8 x - 2$

Step 2

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

$4 x^{2} - 5 x + 6 - 8 x - 2$

Step 3

Subtract $8 x$ from $- 5 x$ .

$4 x^{2} - 13 x + 6 - 2$

Step 4

Subtract $2$ from $6$ .

$4 x^{2} - 13 x + 4$

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