Answer variants:

$x + {\sqrt{2} x}^{2} - {5 x}^{3} - {\frac{7}{2} x}^{4}$

$- 1 + 4 x - {\frac{6}{5} x}^{2} + {7 x}^{3}$

$- 11 - \frac{7}{3} y + y^{2} + {\sqrt{5} y}^{3} + {9 y}^{4}$

${\sqrt{7} x}^{3} + {6 x}^{2} + x - 9$

${9 y}^{4} + {\sqrt{5} y}^{3} + y^{2} - \frac{7}{3} y - 11$

$- 9 + x + {6 x}^{2} + {\sqrt{7} x}^{3}$

${7 x}^{3} - {\frac{6}{5} x}^{2} + 4 x - 1$

$- {\frac{7}{2} x}^{4} - {5 x}^{3} {\sqrt{2} x}^{2} + x$
