5a(4a-7b)+8b(7b-4a)-(4a-7b)= 5a(4a-7b)-8b(4a-7b)-(4a-7b)=(4a-7b)(5a+8b-1)
(4a-7b)*(5a-8b-1)
Объяснение:
5a*(4a-7b)+8b*(7b-4a)-(4a-7b)
5a*(4a-7b)+8b*(-(4a-7b))-(-(7b-4a))
5a*(4a-7b)+8b*(4a-7b)+(7b-4a)
(4a-7b)*(5a-8b)-(4a-7b)
4a-7b)*(5a-8b-1)
5a(4a-7b)+8b(7b-4a)-(4a-7b)= 5a(4a-7b)-8b(4a-7b)-(4a-7b)=(4a-7b)(5a+8b-1)
(4a-7b)*(5a-8b-1)
Объяснение:
5a*(4a-7b)+8b*(7b-4a)-(4a-7b)
5a*(4a-7b)+8b*(-(4a-7b))-(-(7b-4a))
5a*(4a-7b)+8b*(4a-7b)+(7b-4a)
