Odpowiedź:
a)
[tex]14xy - 21 {x}^{2} + 7x {y}^{2} = 7x(2y - 3x + {y}^{2} )[/tex]
b)
[tex] { - 36y}^{2} + 12x - 24y = 12( - 3 {y}^{2} + 1 - 2y)[/tex]
c)
[tex] \sqrt[3]{2} xy + \sqrt[3]{2} - \sqrt[3]{2} z = \sqrt[3]{2} (xy + 1 - z)[/tex]
d)
[tex]9 \sqrt[3]{7} a - 27 \sqrt[3]{7} b - 36 \sqrt[3]{7} = 9 \sqrt[3]{7} (a - 3b - 4)[/tex]
