Answer:
A. 9x^2 - 12x + 4
Step-by-step explanation:
A perfect square trinomial is defined as a trinomial that be derived from squaring binomials.
Through factoring, I am able to gather that 9x^2 - 12x + 4 might be expressed as (3x - 2)(3x - 2)
We can check this using the FOIL method (First Outside Inside Last).
3x times 3x = 9x^2, 3x times -2 = -6x, -2 times 3x = -6x, and -2 x -2 = 4.
This gives us the result of 9x^2 - 12x + 4, making it the correct answer.
(I tried the other three and was not able to get the same result).
