Question

To factor 9x2 - 4, you can first rewrite the expression as:

Answer 1

Answer: It is D or C

Step-by-step

I think it is D or C because 9 times 2 is 18. 18 minus 4 is 14. And all the other equations equal something else. The first one is 3- 2times 2 and that is 4 so that would be one. The second is x minus 4 that would be 8. Then the next would be 9 minus 4. That is 5 so it is either C or D.

Answer 2

Answer:

Option C is correct.

(3x)² - 2²
