2x2 + 3xy + y2

2x2 + 2xy + xy + y2

2x(x + y) + y(x + y)

Take out common term x + y

(x + y)(2x + y).

Can't be factored.


1) If it says to "factor" and it's too hard then stop and say "Unfactorable." Probably you should try the Q.F. because something might have slipped by you and it's really easy to factor. 

2) If it says "solve", set it equal to zero, try to factor it. If it's hard to factor, use the Quadratic Formula. 
Or you can use the Q.F. to start with.
