Hey guys! So I was wondering why the systematic name of a polymer, for example polyethylene, ended in -ene. I always understood the -ene suffix as the ending of alkenes because of the double bond. This works with the monomers too since there is still the double bond, but why does it remain as...

The cubic equation x^3 + kx + 1 = 0, where k is a constant, has roots α, β and γ. For each positive integer n, Sn = αn+βn+γn. i/ State the value of S1 and express S2 in terms of k. ii/ Show that for all n, Sn+3 + kSn+1 + Sn = 0 iii/ Hence, or otherwise, express α4+β4+γ4 in terms of k. I'm...
