Step 1.1

Remove parentheses.

$8 + 6 x^{2} - 5 x + x + x^{2} - 1$

Step 1.2

Subtract $1$ from $8$ .

$6 x^{2} - 5 x + x + x^{2} + 7$

$6 x^{2} - 5 x + x + x^{2} + 7$

Step 2

Add $6 x^{2}$ and $x^{2}$ .

$7 x^{2} - 5 x + x + 7$

Step 3

Add $- 5 x$ and $x$ .

$7 x^{2} - 4 x + 7$

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