alukav5142 [94]3 years ago
5 0

Answer:

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

Step-by-step explanation:

I don't know how much more i can explain, except that you could use the quadratic formula to get your zeroes and then put it in your answer. But this one is obvious. Whenever there isn't an x term and you're subtracting the constant term, it's usually (ax - b)(ax + b)
