1) ac + ad + 2bc + 2bd =
= (ac + ad) + (2bc + 2bd) =
=a(c + d) + 2b(c + d) =
=(c + d)*(a + 2b);
3) x²y - z²x + y²x - z²y =
= (x²y + y²x) - (z²x + z²y) =
=xy(x + y) - z²(x + y) =
=(x + y)*(xy - z²);
5) а³ + 2 + а + 2а² =
= (а³ + 2а²) + (а + 2) =
= а²(а + 2) + (а + 2) =
= (а + 2)*(а² + 1);
7) х³ + х - 3ху + 2 + 2х² - 6у =
= (х³ + 2х²) + (х + 2) - (3ху + 6у) =
= х²(х + 2) + (х + 2) - 3у(х + 2) =
= (х + 2)*(х² + 1 - 3у);
9) 4ах + 2ау - аz - 4bx - 2by + bz =
= (4ax - 4bx) + (2ay - 2by) - (az - bz) =
= 4x(a - b) + 2y(a - b) - z(a - b) =
=(a - b)*(4x + 2y - z).
