2) x^2 - xy - 2x + 2y = (x^2 - xy) + (-2x + 2y) = x (x - y) - 2 (x - y) = (x - y) (x - 2);

4) a^2 - ab - 3a + 3b = (a^2 - ab) + (-3a + 3b) = a (a - b) - 3 (a - b) = (a - b) (a - 3);

6) 6by - 15bx - 4ay + 10ax = (6by - 15bx) + (-4ay + 10ax) = 3b (2y - 5x) - 2a (2y - 5x) = (2y - 5x) (3b - 2a);

8) 4x^2 - 4xz - 3x + 3z = (4x^2 - 4xz) + (-3x + 3z) = 4x (x - z) - 3 (x - z) = (x - z) (4x - 3).
