Question

Hi...given this 4th degree trinomial: x4 + x2 +1, factor complete into product of two second degree trinomials and check(to obtain x4+x2+1). Please help, thank you.

Answer 1

x4 + x2 +1
=x4 + 2x2 +1 -x2
=(x^2+1)^2 - x^2
=(x^2+1 +x)(x^2+1-x)

Answer 2

I've noticed you've expressed the exponents a bit different. Does this affect the answer? Just the same....thank you so much.

Answer 3

just the same
no difference
