Answer 2

Option C = 9x^2 - 4

Explanation:

The given values are three 'x' plus two that is entirely multiplied the three 'x' minus two. Expanding it further that is nine 'x' minus six 'x' entirely multiplied by six 'x' minus four, the entirely value calculation. The final answer from maximum expansion will be nine 'x' to the power of two that is further minus by four. The numeric calculation are given below:

(3x+2) (3x-2)

(9x - 6x) (6x -4)

3x * 6x -4

9x^2-4
