How to factor a trinomial when its in a different order ?
Like 49x^2 - 28xy + 4y^2
how do you get it in x^2 - x - 12 format ?

You can't get it in that format, since it has two variables x and y. but you know the factorization will be of the form
( _ x + _ y) ( _ x + _ y)
and its a matter of filling in the blanks to get the coefficients right. Once you realize that, the problem is no more difficult than factoring 49x^2 - 28x + 4. there are just some extra y's flying around!
In this case, you get
(7x + 2y) (7x + 2y) = (7x + 2y)^2
