Multiply the "Special Case" binomial. (x−y)^2

A. x^2−2xy+y^2
B. x^2+y^2
C. x^2−y^2
D. x^2−2xy−y^2

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
