Answer 1

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.
