Question

(a²-b²)³ + (b²-c²)³ + (c²+a²)³

Answer 1

Answer:

hey mate

{(a²)³-(b²)³-3a²b²(a²-b²)}

a^6-b^6-3a⁴b²+3a²b⁴

similarly in two of others

so, (b²-c²)³=b^6-c^6-3b⁴c²+3b²c⁴

same, (c²+a²)³= c^6+a^6+3c⁴a²+3c²a⁴

add them(a^6-b^6-3a⁴b²+3a²b⁴)+(b^6-c^6-3b⁴c²+3b²c⁴)+(c^6+a^6+3c⁴a²+3c²a⁴)

{further solve it yourself.........

hope it'll help you....✌️
