Answer 2

Answer:

({a - b ) - (a + b )}

if we will open the bracket (a -b ) then this minus sign will become + bcoz of the minus sign outside the bracket

we know - ,- = +

so... a + b - a + b = 0

for eg .. let a be 2 and b be 1

2+ 1- 2+1

3-3 =0

similarily here also answer is 0

HOPE YOU GET IT....HAVE A NICE DAY AHEAD:)
