Answer:
The answer will be 2ab - a^2(option A).
Step-by-step explanation:
Let the expression which is to be added to (a^2 + 2ab + b^2) be x.
Thus, mathematically we can write that;
(a^2 + 2ab + b^2) + x = 4ab + b^2
a^2 + 2ab + b^2 + x = 4ab + b^2
x = 4ab + b^2 - (a^2 + 2ab + b^2)
x = 4ab + b^2 - a^2 - 2ab - b^2
= 2ab - a^2.
Thus, (2ab - a^2) should be added to (a^2 + 2ab + b^2) to get (4ab + b^2).
That's all.
