Question
So the problem is x^2+2x+xy+2y and i know how to factor using the box method using 3 terms but i dont know how to do that with four

Answer
I'm not sure if this is the box method, but I would note that the 1st two terms both have an x that could be factored out.  This gives x(x+2).  The last two terms both have a y that can be factored out.  This gives y(x+2).  Note that both have the factor (x+2).  One has x as the other term and the other has y.  This makes it (x+y)(x+2).
