L = a - b - c
R = a - b + c
-R = -a + b - c

Hence, L - R = a - b - c - a + b - c = -2c

Option E

L-R= a-b-c-a+b-c=-2c

So correct answer is option E.

L = (a - b)- c = a - b - c
R = a - (b - c) = a - b + c

L - R = a - b - c - (a - b + c) = a - b - c - a + b - c = -2c

Hence, E.

(A) 2b

(B) 2c

(C) 0

(D) -2b

(E) -2c


\(L = a - b - c\)

\(R = a - b + c\)

So, \(L - R = (a - b - c ) - ( a - b + c )\)

Or, \(L - R = a - b - c - a + b - c\)

Or, \(L - R = - 2c\), Answer must be (E)

L=a−b−c

R=a−b+c


So,
L−R=(a−b−c)−(a−b+c)

Or,
L−R=a−b−c−a+b−c

Or,
L−R=−2c
Answer must be (E)
