Question

ЕТО НАДО ПРЯМ ШАС!!!!!!!! ПО АЛГЕБРЕ!!!!!!!

Answer 1

1) 17ab - 34a + b² - 2b = (17ab - 34a) + (b² - 2b) = 17a(b - 2) + b(b - 2) =

= (b - 2)(17a + b)

Ответ : A

2) 42am + 16 mu - 12au - 56m² = (42am - 56m²) + (16mu - 12au) =

= 14m (3a - 4m) + 4u(4m - 3a) = 14m(3a - 4m) - 4u(3a - 4m) =

= (3a - 4m)(14m - 4u)= 2(3a - 4m)(7m - 2u) = (6a - 8m)(7m - 2u)
