Best ResponseYou've already chosen the best response.0The factors are of the form (ax + by + c)(dx+ey+f) Hopefully you can work out a few of those letters immediately (by the coefficients of x^2 and y^2), and then the last few

Best ResponseYou've already chosen the best response.0You look at the first three terms and you factor those three. x^2 + 12x + 36 = (x + 6)(x + 6) which is (x + 6)^2 then you have (x + 6)^2  y^2 so you have the difference of two squares. (x + 6 + y)(x + 6  y) is the answer

Best ResponseYou've already chosen the best response.0Damn, I actually prefer your method, but I guess I am used to factorising things where comparing coefficients is the only way and there are no neat tricks such as that.
