Answer:
Step-by-step explanation:
Eliminate the last two possible answers immediately, because their constants are negative. A perfect square trinomial MUST have a positive constant.
If we factor the first answer choice, we get (3x - 2)(3x - 2) = 9x^2 - 12x + 4. This is a perfect square trinomial.
Looking at the second answer choice: (4x - 3)(4x - 3) = 36b² - 24x + 9. This is also a perfect square trinomial.
Please note: Please use " ^ " to indicate exponentiation:
9x^2 is correct; 9x2 is incorrect.
