= 2a(4a²+b²+c²+2ab-bc-2ca)+b(4a²+b²+c²+2ab-bc-2ca)+c(4a²+b²+c²+2ab-bc-2ca)
= (8a³+2ab²+2ac²+4a²b-2abc-4ca²)+( 4a²b+b³+bc²+2ab²-b²c-2bca)+(4a²c+b²c+c³+2abc-bc²-2c²a)
= (8a³+2ab²+2ac²+4a²b-2abc-4ca²)+( 4a²b+b³+bc²+2ab²-b²c-2bca)+(4a²c+b²c+c³+2abc-bc²-2c²a)

Answer:
Step-by-step explanation:
= 2a(4a²+b²+c²+2ab-bc-2ca)+b(4a²+b²+c²+2ab-bc-2ca)+c(4a²+b²+c²+2ab-bc-2ca)
= (8a³+2ab²+2ac²+4a²b-2abc-4ca²)+( 4a²b+b³+bc²+2ab²-b²c-2bca)+(4a²c+b²c+c³+2abc-bc²-2c²a)
