Question

if a minus b whole cube plus B minus C whole cube plus c minus a whole cube equal to 3 k then the value of a cube minus b cube into a cube minus b cube into C³ minus a³ upon k ?

Answer 1

( a - b )^3 + ( b - c )^3 + ( c - a )^3

if a + b + c = 0 , then ( a - b )^3 + ( b - c )^3 + ( c - a )^3

sum = a - b + b - c + c -a = 0

( a - b )^3 + ( b - c )^3 + ( c - a )^3 = 3 ( a-b ) (b - c )(c -a) Ans.
