1/2 + 1/3 - 1/4 = I don't know

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

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?
