3ax^2  27a
You can factor that into
3a (x^2  9), which also equals
3a(x3)(x+3).
It is not clear from your question what you are supposed to do with that algebraic expression. If it were equal to zero, x would be +3 or 3.
If you are expected to factor, try factoring out 3a first: 3a(x^2  9)
You can also factor x^2  9. Can you determine those factors?
I hope this helps.
