Step 1.1.1

Move $1$ .

$- p \cdot (2 \cdot p^{2} - 3 p - 1) - (- 2 \cdot p + p^{2} + 1) \cdot (2 p^{2})$

Step 1.1.2

Reorder $- 2 \cdot p$ and $p^{2}$ .

$- p \cdot (2 \cdot p^{2} - 3 p - 1) - (p^{2} - 2 \cdot p + 1) \cdot (2 p^{2})$

Step 1.1.3

Remove parentheses.

$- p \cdot (2 \cdot p^{2} - 3 p - 1) - (p^{2} - 2 \cdot p + 1) \cdot 2 p^{2}$

Step 1.1.4

Move $p^{2} - 2 \cdot p + 1$ .

$- p \cdot (2 \cdot p^{2} - 3 p - 1) - 1 \cdot 2 p^{2} (p^{2} - 2 \cdot p + 1)$

Step 1.1.5

Reorder $- p \cdot (2 \cdot p^{2} - 3 p - 1)$ and $- 1 \cdot 2 p^{2} (p^{2} - 2 \cdot p + 1)$ .

$- 1 \cdot 2 p^{2} (p^{2} - 2 \cdot p + 1) - p \cdot (2 \cdot p^{2} - 3 p - 1)$

Step 1.2

Factor $- p$ out of $- 1 \cdot 2 p^{2} (p^{2} - 2 \cdot p + 1)$ .
