WebbThe sum of the squares of all six roots is thus given by 2(tan2(20 ∘) + tan2(40 ∘) + tan2(80 ∘)). However, if we write these roots as r1,..., r6, then we also have ∑ i r2i = (∑ i ri)2 − 2∑ i < jrirj But ∑iri is the coefficient of x5 in the above equation, namely zero, and ∑i < jrirj is the coefficient of x4, namely − 33.
