Respuesta :

The answer is : 

3x² ( 4x² + 6x + 15)

Answer: so is the answer 3^2 or the other?

Step-by-step explanation:

well anyway but what I know the answer should be the second thing because you want the numbers to be the LCM which for this it would be (4x^2 + 6x + 15) but not 100% bout this
