Question

what we be the answer​

Answer 1

Answer:

Identity used: If a+b+c = 0, then a³ + b³ + c³ = 3abc

3x = a + b + c

=> x + x + x = a + b + c

On transposing (a+b+c) from RHS to LHS,

=> (x-a) + (x-b) + (x-c) = 0

Let x-a = m, x-b = n, x-c = o.

=> m + n + o = 0 (eqn 1)

And on putting these values in the question's expression,

we get, m³ + n³ + o³ -3mno

[since, m+n+o = 0 (eqn 1)

=> m³ + n³ + o³ = 3mno]

= 3mno - 3mno

= 0

Thus, correct answer is (c) 0
