(a+b)³=(a+b)(a²-2ab+b²)
56am+27mu-24au-63m²=56am-24au+27mu-63m²=8a(7m-3u)+9m(3u-7m)=8a(7m-3u)- 9m(7m-3u)=(7m-3u)(8a-9m)
ответ: (7m-3u)×(8a-9m)
(8a-9m)(7m-3u)
Объяснение:
=8a(7m-3u)-9m(7m-3u)=(8a-9m)(7m-3u)
(a+b)³=(a+b)(a²-2ab+b²)
56am+27mu-24au-63m²=56am-24au+27mu-63m²=8a(7m-3u)+9m(3u-7m)=8a(7m-3u)- 9m(7m-3u)=(7m-3u)(8a-9m)
ответ: (7m-3u)×(8a-9m)
(8a-9m)(7m-3u)
Объяснение:
=8a(7m-3u)-9m(7m-3u)=(8a-9m)(7m-3u)
