1. No.

2. Difference of two squares.

3. "sum", "subtraction".

Step-by-step explanation:

The original expression: 4n² - 25

1. Are there any common factors?

No, since there isn't a number or variable that can divide both parts at the same time.

2. The expression is the difference of two squares.

3. So the factored form is the sum of the square roots times the subtraction of the square roots. (2n + 5)*(2n - 5)
