Answer :
Now,
(a - b + c)² + (b - c + a)² + 2 (a - b + c) (b - c + a)
= { (a - b + c) + (b - c + a) }²
= ( a - b + c + b - c + a )²
= ( 2a )²
= 4 a²
IDENTITY RULE :
(a + b)² = a² + b² + 2ab

Now,
(a - b + c)² + (b - c + a)² + 2 (a - b + c) (b - c + a)
= { (a - b + c) + (b - c + a) }²
= ( a - b + c + b - c + a )²
= ( 2a )²
= 4 a²
IDENTITY RULE :
(a + b)² = a² + b² + 2ab
