Answer 1

what's the question?

Answer 2

I have to factor it @kl0723

Answer 3

If you want to factorise that expression, use the idea of difference between two squares and work backwards. If you use difference between two squares to get a similar result like \[x^{4} -1\]
Then what would it be?

Answer 4

How would you write an expression that would allow you to use difference between two squares in order to get that expression you just wrote there?
