(5c-3)(c+2) = 5c^2+10c-3c-6
(c-4)(2-5c) = 2c-5c^2-8+20c
5c^2+10c-3c-6+2c-5c^2-8+20c = 29c - 14
29c-14
Объяснение:
(5с-3)(с+2)+(с-4)(2-5с)=5c*c+10c-3c-6+2c-5c^2-8+20c=29c-14
(5c-3)(c+2) = 5c^2+10c-3c-6
(c-4)(2-5c) = 2c-5c^2-8+20c
5c^2+10c-3c-6+2c-5c^2-8+20c = 29c - 14
29c-14
Объяснение:
(5с-3)(с+2)+(с-4)(2-5с)=5c*c+10c-3c-6+2c-5c^2-8+20c=29c-14
