Help me write an equation to solve, please!

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

What is the solution to the equation below? 3/x-2+6=square root x-2 +8
