Ответ:

$0.3 {x}^{3} - {x}^{3} + 0.9 {x}^{3} + 3 {x}^{3} = {x}^{3} (0.3 - 1 + 0.9 + 3)$

${y}^{3} - \frac{1}{3} {y}^{3} - \frac{1}{3} {y}^{3} + 4 {y}^{3} = {y}^{3} (1 - \frac{1}{3} - \frac{1}{3} + 4)$

$- x {y}^{3} - x {y}^{3} - 0.8x {y}^{3} + 1.9x {y}^{3} = x {y}^{3} ( - 1 - 1 - 0.8 + 1.9)$

$\frac{1}{3} xy + xy - \frac{1}{6}xy \: + 3xy = xy( \frac{1}{3} + 1 - \frac{1}{6} + 3)$
