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

Sketch one cycle if the cosine function y=2cos2theta

Which number completes the inequality? 2/3 < _ < 7/9
