In the coordinate plan (-6,9) b (3,9) c (3,3) def is shown in the coordinate plan below

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

Math it's appreciated. (picture provided)
