Answer :
Answer:
2a²+ 0 + a
Explanation:
The additive identity property says that when we add 0 an a number, the result is the same number, so:
x + 0 = x
Since the 4th option is the only one with a zero in the expression, we can apply the additive identity property and simplify as:
2a²+ 0 + a
2a²+ a
Therefore, the answer is 2a²+ 0 + a
