Answer:
(-5) is smallest integer to be added.
Explanation:
In the given expression we have to identify the smallest integer to be adeed so that it is divisible by (m+1).
If we divide the expression then we get quotient (-2m²+3m-4) and the remainder is +5.
Therefore we can say that if we subtract 5 from the given expression it will be divisible by (m+1).
So the answer is (-5) is the smallest integer to be added.
