Find the HCF and LCM of:
1 + 4x + 4x^2 - 16x^4.. ,1 + 2x - 8x^3 - 16x^4.., 16x^4 + 4x^2 + 1

what's with the .. ?
nothing. that is just to separate the equations.. please help
hmmm. None of the polynomials factors over the reals, so I don't see any help there.
Looks like GCF=1 and
LCM = (1+4x+4x^2-16x^4)(1+2x-8x^3-16x^4)(16x^4+4x^2+1)
if
x=-1 we have -17,-7,21
x=0 we have 1,1,1
x=1 we have -7,-21,21
x=2 we have -231,-315,273
