The answer is A

9x² - 12x + 4
9x² - 6x - 6x + 4
3x(3x) - 3x(2) - 2(3x) - 2(-2)
3x(3x - 2) - 2(3x - 2)
(3x - 2)(3x - 2)
(3x - 2)²

I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.

My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
