C:
D:
Correct Answer
D
Explanation
9ysup3 -16xsup23sup2 - 4sup2xsup2(3y - 4x) (3y +4x)To factorize completely the expression 9y² - 16x², we can use the difference of squares formula, which states that a² - b² can be factored as (a + b)(a - b).In this case, we have 9y² - 16x², which can be rewritten as (3y)² - (4x)².Using the difference of squares formula, we can factorize it as follows:(3y + 4x)(3y - 4x)Therefore, the expression 9y² - 16x² can be completely factorized as (3y + 4x)(3y - 4x).
