Dec 20, 2015 · How do you factor the expression x8 − 1? Use some identities to find: x8 −1 = (x − 1)(x + 1)(x2 + 1)(x2 +√2x + 1)(x2 − √2x + 1) We shall use some identities to help: The difference of squares identity: a2 −b2 = (a −b)(a +b) Consider also: (a2 + kab +b2)(a2 − kab + b2) = a4 +(2 −k2)a2b2 + b4. In particular if k = √2 then:
