How do you factor a difference of two squares? Is there a similar strategy for

Also, in my example above for the difference of squares I was using "perfect" squares. If you look at the equation itself

x2 - c2 = 0 and then add c2 to both sides you get

x2 = c2 and that x = ±vc2

so for something like x2 - 10 = 0 you would get x = ±v10.

In factor form:

(x+v10)(x-v10) = 0
