hi reallylongnickname

You cannot 'solve' it anyway because it is not an equation; rather just an expression.

So I think you mean 'simplify' it.

It factorises (factorizes) as you have correctly done in your last line.  That's it done.

The way to solve this is apparently to use division by the common factor which is 3x^2

However, if I solve it with out the division like this (see below), I get the same answer. So what rule should I be following? Am I skipping steps or am I using different method?
