The difference of two squares is equivalent to the sum, times the difference, of the numbers that are squared. In symbols:
a2 - b2 = (a + b)(a - b)
Here is an example with numbers: 102 - 92 = (10+9)(10-9)
x2 - 64 is a type of expression called a "Difference of squares". That would be any binomial that is a perfect square subtracted from another perfect square. Any binomial in that format can be factored out to two binomials multiplied by each other. If it's in the format a2 - b2, then it can also be expressed as (a + b)(a - b). In this case then, it would come out as: (x + 8)(x - 8)

The answer is 230.
This is when two perfect squares(ex.) [x squared minus 4] a question in which there are two perfect squares. you would find the square root of each. then it depends on what kind of math your doing.
Since a thousand squared is a million, the "smallest..." is the square of 1001, and the "largest..." is the square of 999.
Difference
The word "difference" implies subtraction. The word "squares" implies a perfect square term or number. To recognize the "difference of squares" look for 2 perfect square terms, one being subtracted from the other. Ex. x2 - 16. "x" is being squared and 16 is a perfect square. They are being subtracted. Factors: (x+4)(x-4)

what is the process of writing a expression as a product? is it Factoring, Quadractic equation, perfect Square trinomial or difference of two squares
How about: 100-64 = 36 as one example
