Alright I'm doing a maths review (grade 11) and on the page, the subtitle says "Quadratics" and then underneath is the questions, no instructions. I figured out the first one "y^2+2y+1" and got to "(y+1)^2", but the second question is "49(2yw)^2".
I can't figure out what to do with it... should I expand it out and deal with it or will I get right back to that? I think maybe it's confusing me because it's in a different format, but I'd like some help, thanks.

The second is a difference of two squares.
7^2u^2 where u=2yw

Thank you so much for clarifying, I think it was a little foggy in my mind because it looked different from the others, but now that you say difference of squares, it makes total sense... I'll have to keep that in mind for the test!
