Question

(-a-3,4b+3c)*(-d)
-0,8a(4p-5b-1,2)
-14(3/7x-9/14y+0,5z-0,2)
Вынесите за скобки общий множитель:
8m-8n
7mn-2mp+m
12xy+18xk

Answer 1

(-a - 3.4b + 3c) * ( - d) = ad +3.4bd - 3cd
====
-0.8a(4p -5b - 1.2) = -3.2ap +4ab + 0.96a
====
-14*(3/7x - 9/14y + 0.5z - 0.2) = -6x + 9y - 7z + 2.8
====
8m - 8n= 8(m-n)
===
7mn - 2mp + m = m(7n - 2p +1)
==
12xy + 18xk = 6x*(2y + 3k)
