What is the special case of difference of squares?
What is the special case of difference of squares?
What if we had a set of factors like this:
(x + 5)(x - 5)
What happens when we FOIL this?
So, how does difference of squares work?
If you have an expression that can be written this way, you can factor is using this shortcut:
Let's do some examples:
