Hi guys. how are u all, first to answer gets branliest :)

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Can someone me with this? i’m not sure what to put for my equations.

How can you check that you have correctly converted frequencies to relative frequencies?
