You can factor that into

3a (x^2 - 9), which also equals

3a(x-3)(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.
