Question

. If 3x = a +b+c, then the value of (x – a)? +(x - b)+ (x–c) - 3 (x – a) (x – b) (x –c) is
(b) (a - b)(b -c) (c-a)
(c) o
(d) none of these
(a) a+b+c​

Answer 1

Answer:

Option (C)

Step-by-step explanation:

Explanation

(x-a) +(x-b) +(x-c) = 3x-(a+b+c) (1)

¢given that :- 3x=a+b+c

From equation (1)

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

So,

(x-a) ^3+(x-b)^3+(x-c)^3 - 3(x-a)(x-b)(x-c) =0

Answer:- (x-a) =0
