a. (x)(x/2) = 22.5
b. 1/2(x + x/2) =22.5
c. x + x/2= 22.5
d. x + 2x =22.5

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
