Pls help with my geometry!(question 3)

Polynomial that can be factored as (3x-4)(3x+4)

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

Which expression shows the sum of the polynomials with like terms grouped together
