Answer:
To find the answer, we simply have to substitute the values for a and b that the question gave us into the expression.
In this case, that would be substituting a = -1 and b = 2 into -3ab - 2.




Hence, the answer is 4. However, there is no option with 4 for Question 3, so I would suggest OP to check the question again to confirm if there is no option with the answer as 4.
