$8 x - 10 x^{2} - 13 x - 9 x^{2} + 6 x$

Step 1

Subtract $13 x$ from $8 x$ .

$- 10 x^{2} - 5 x - 9 x^{2} + 6 x$

Step 2

Subtract $9 x^{2}$ from $- 10 x^{2}$ .

$- 19 x^{2} - 5 x + 6 x$

Step 3

Add $- 5 x$ and $6 x$ .

$- 19 x^{2} + x$

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