x^2 - 64.
There is a formula for the "difference of squares." In this case, the answer is (x + 10)(x - 10)
-79
It is x^2 -4 = (x-2)(x+2) when factored and it is the difference of two squares
You must use the difference of squares formula: x2 - y2 = (x + y)(x - y) Thus: x2 - 25 = (x + 5)(x - 5).
So x4 - 1 is the difference of squares, so x4 - 1 = (x2 - 1)(x2 + 1) = (x + 1)(x - 1)(x2 + 1).
You could factor this as a difference of squares, but because 8 is not a perfect square, you would wind up with radicals in your answer: x2 - 8 = (x + √8)(x - √8) = (x + 2√2)(x - 2√2)
It is the difference of two squares which is: (x+2y)(x-2y)
It is the difference of squares. (x-4) and (x+4) <--- answer
(x + 3)(x - 3)
There is a formula for the "difference of squares." In this case, the answer is (x + 10)(x - 10)
There's a formula for the "difference of squares." (x + 1)(x - 1)
There is a formula for the "difference of squares." In this case, the answer is (x - 17)( x + 17)
There is a formula for the "difference of squares." In this case, the answer is (x + 9)(x - 9)
There is a formula for the difference of squares. If that's x2 - 144, the answer is (x - 12)(x + 12)
x2-121 = (x-11)(x+11) when factored which is the difference of two squares

First you should take out the common factor. After you do that, in this case you have a difference of square, so you can use the formula for a difference of squares.
