а) a·(b - c) + d·(c - b) = a·(b - c) - d·(b - c) = (a - d)·(b - c)

б) x·(y - 5) - y·(5 - y) = x·(y - 5) + y·(y - 5) = (x + y)·(y - 5)

в) 3a·(2x - 7) + 5b·(7 - 2x) = 3a·(2x - 7) - 5b·(2x - 7) = (3a - 5b)·(2x - 7)

г) (x - y)² - a·(y - x) = (x - y)² + a·(x - y) = (x - y)·(x - y + a)

д) 3·(a - 2)² - (2 - a) = 3·(a - 2)² + (a - 2) = (a - 2)·(3a - 6 + 1) = (a - 2)·(3a - 5)

е) 2·(3 - b) + 5·(b - 3)² = 5·(b - 3)² - 2·(b - 3) = (b - 3)·(5b - 15 - 2) = (b - 3)·(5b - 17)
