1, $x^{3} - x^{2} + x - 1$ ^ $x^{3} - x^{2} + x - 1$ ^ $x^{3} - x^{2} + x - 1$

2, $6 x^{2} y - 2 x y^{2} + 3 x - y$ ^ $6 x^{2} y - 2 x y^{2} + 3 x - y$ ^ $6 x^{2} y - 2 x y^{2} + 3 x - y$

3, $4 x^{2} + 1$ ^ $4 x^{2} + 1$

4, $x^{2} - 9 x + 8$ ^ $x^{2} - 9 x + 8$

5, $x^{3} - 2 x^{2} y + 3 x y^{2}$ ^ $x^{3} - 2 x^{2} y + 3 x y^{2}$ ^ $x^{3} - 2 x^{2} y + 3 x y^{2}$ ^ $x^{3} - 2 x^{2} y + 3 x y^{2}$

6, $x^{2} - 6 x + y - y^{2}$ ^ $x^{2} - 6 x + y - y^{2}$ ^ $x^{2} - 6 x + y - y^{2}$

7, $x^{2} - x y - 2 x + 2 y$ ^ $x^{2} - x y - 2 x + 2 y$
