Niels Henrik Abel, wekuNorway, uye Évariste Galois, wekuFrance, vakaratidza kuti hapana nzira yakajairika yealgebra yekugadzirisa polynomial equations yedhigirii yakakura kudarika ina (Abel<unk>Ruffini theorem). Vamwe vezana ramakore rechi19 masvomhu vakashandisa izvi mukuratidzira kwavo kuti straightedge nekambasi chete hazvina kukwana kuti zvigadzirise kona yakasarudzika, kuvaka divi re cube kaviri vhoriyamu yecube yakapihwa, kana kuvaka mativi akaenzana nenzvimbo kune denderedzwa rakapihwa. Masvomhu akange aedza zvisina maturo kugadzirisa zvese izvi matambudziko kubvira panguva yevaGiriki vekare. Kune rimwe divi, muganho wenhamba nhatu mu geometry wakapfuudzwa muzana ramakore rechi19 kuburikidza nekutarisa kwenzvimbo uye hypercomplexity parameter.
