57 divided by 970 and I need the problems.

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

If the discriminant if a quadratic equation is 4 which statement describes the roots?

How many ordered pairs of positive integers satisfy xy=32?
