If you could add a picture or tell me what the picture shows that would be great!
The answer is 9
One square is equal to one. for the rest just substitute the x and y for the given values
When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)
The answer is 1;3 because if you simplified 2;6 you get 1;3 so the answer to that is
a: 1;3
