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?

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.
