\frac{1}{m-2}-1
This expression is the difference of squares. It can be factored to (9 - 7n4)(9 + 7n4)

The difference of 2 squares ca n be expressed as: x2 - y2
There are: 8*8 = 64 squares
First, take out the common factor, then use the formula for the difference of two squares.2m2 - 8= 2(m2 - 4)= 2(m+2)(m-2)

\frac{1}{m-2}-1
x^2 - 64.
This expression is the difference of squares. It can be factored to (9 - 7n4)(9 + 7n4)

"Difference" implies subtraction. Example: The difference of 8 and 5 is 3 because 8 - 5 = 3. To determine if a polynomial is the difference you probably have to subtract one polynomial from another and check if your answer matches a given polynomial. To clarify the above, the polynomial should be able to be factorised into two distinct factors. For example x^2 - y^2 = (x + y)(x - y). This is the difference of two squares.
