Factor 81n2 - 100 : ___.
- A (9n - 10)2
- B (81n + 10) (n - 10)
- C (9n - 10) (9n + 10)
- D (9n + 10)2
That's Correct!
It's Wrong!
The given expression can be factored using the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). In this case, a = 9n and b = 10. Therefore, the expression can be factored as (9n - 10)(9n + 10).
