Simplify this algebraic fractions HELP!!

I need to simplify this algebraic fraction: (with / being the fraction)

12^2 - 6h / 27h^2 - 18h

Please help me - I've been stuck for about half an hour
The answer should be 2(2h -1) / 3(3h - 2)

Factorise both the numerator and the denominator. For example, the numerator should become 6h(2h-1).

Then you can cancel out factors to simplify the fraction.

Would the denominator be 3h(9h - 6)?
