Week 2- Something I thought was "cool"

Something I found very interesting/cool was the many different ways you explained that you could factor. Sometimes some ways worked better for specific problems. There was the "guess and check" method which is what I've always done, but when I was introduced to the Square and Diamond method, I found that that method could help me out much more efficiently than going through all the possible outcomes and sorting through which were correct. I was very enlightened because I had never seen that before and actually could comprehend it. You explained it in a very understandable format and I thought it was a neat trick to get the job done. Thank you so much!
