How am i going to break down 14x25x4 using the strategy distributive property

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
