None of the given options are correct.
To correctly factor 9x^2-16, we can use the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b).
In this case, a = 3x and b = 4. Therefore, we have:
9x^2 - 16 = (3x)^2 - 4^2
= (3x + 4)(3x - 4)
So the correct factored form of 9x^2-16 is (3x + 4)(3x - 4).
Factor 9x^2-16
(3x+4)(3x-4)
(3x+4)(3x+4)
This expression cannot be factored.
(3x-4)(3x-4)
