How would 3x^227y^2 be factored completely?

algebra 2 
bobpursley,
isnt it the difference of two squares?
3(x^29y^2)=3(x3y)*(x+3y)

Yes but isnt the difference of two squares just one technique to factor polynomials?

bobpursley,
Of course. If one technique works to factor a polynomial, it is factored.
