Find the value of each expression z=1, when z=2, and when z=3. Then identify which expressions are equivalent. 1. 9z-4-3z

2. 2(3z-2)

3. 9z-4z-3

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
