Answer:
C
Step-by-step explanation:
This can be factored using the rule [tex]a^2-b^2=(a+b)(a-b)[/tex]
We can write the question shown as:
[tex]9x^2-16y^2\\=(3x)^{2}-(4y)^2[/tex]
Now we take 3x as a, and 4y as b and put it into the formula:
[tex](3x)^{2}-(4y)^2\\=(3x+4y)(3x-4y)[/tex]
Answer choice C is correct.
