Question

помогите решить пример

Answer 1

c³+c²d-cd²-d³+6c²d--6cd²+10cd²-10c²d=c³-3c²d+
+3cd²-d³=c²d-cd²+6c²d--6cd²+10cd²-10c²d=-3c²d+3cd²
c²d+6c²d-10c²d+3c²d=0
cd²-6cd²+10cd²-3cd²=0
Ответ равен 0

Answer 2

c³+c²d-cd²-d³+6c²d--6cd²+10cd²-10c²d=c³-3c²d+
+3cd²-d³=c²d-cd²+6c²d--6cd²+10cd²-10c²d=-3c²d+3cd²
c²d+6c²d-10c²d+3c²d=0
cd²-6cd²+10cd²-3cd²=0
