If x = a – b, y = b – c, z = c – a, then the numerical value of the algebraic expression x3 + y + z – 3xyz will be
Correct Answer: 0
Explanation:
Here , x = a – b, y = b – c, z = c – a
We have x + y + z = a – b + b – c + c – a = 0
∴ x3 + y + z – 3xyz = 0
Hence , the numerical value of algebraic expression is 0 .
