$(x^{2} + 8 x + 8) + (- 10 x^{2} + 5 x)$

Step 1

Remove parentheses.

$x^{2} + 8 x + 8 - 10 x^{2} + 5 x$

Step 2

Subtract $10 x^{2}$ from $x^{2}$ .

$- 9 x^{2} + 8 x + 8 + 5 x$

Step 3

Add $8 x$ and $5 x$ .

$- 9 x^{2} + 13 x + 8$

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