1. а) 2x^2 xy = x * (2x y).

б) ab + 3ab^2 = ab * (1 + 3b).

в) 2y^4 + 6y^3 4y^2 = 2y^2 * (y^2 + 3y 2).

г) 4y^4 + 4y = ax ay; 4y * (y^3 + 1) = a * (x y).

2. a) 2a^2b 6ab^2 + 2^3b = 2b * (a^2 3ab + 4).

b) 3x xy 3y + y^2 = 3 * (x y) y * (x y) = (x y) * (3 y).

c) x^2 * (x 1) + x * (x 1) = x * (x 1) * (x + x 1) = x * (x 1) * (2x 1).

d) ax ay + cy cx + x y = a * (x y) c * (x y) + x y = (x y) * (a c + 1).

3. xy + 3x + 2x = xy + 5x = x * (y + 5).

Если х = 2 + 2/3 = 8/3, у = 3 + 2/3 = 11/3, то 8/3 * (11/3 + 5) = 208/9 либо 23 целых 1/9.
