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
