7.211; Starting from the left to right, x1=3 x2=7, y1=2 y2=8. Plug these in to the distance formula
(7-3)^2+(8-2)^2
(4)^2+(6)^2
16+36
sqrt 52

<h2>Explanation:</h2><h2></h2>
If we can write a polynomial in the form , then we can factor it as:
In this problem, we have the following expressions:
- For 1 and 4 we can't write this in the form
so this is not a difference of squares.
- For 2:
So we could write 2 as a difference of squares.
- For 3:
So we could write 2 as a difference of squares.
