By the time Jerrard discovered the transformation, Ruffini 's work and Abel 's work on the impossibility of solving the quintic and higher order equations had been published. However, at the time of Bring's discovery, there was no hint that the quintic could not be solved by radicals and, although Bring does not claim that he discovered his transformation in an attempt to solve the quintic, it is likely that this is in fact why he was examining quintic equations.
Ng oras Jerrard natuklasan ang pagbabagong-anyo, Ruffini 's trabaho at Abel' s trabaho sa ikaaari ng tuos ang quintic at mas mataas na-order ng equation ay nai-publish na. Subalit, sa oras ng Dalhin's diskubre, wala ang parinig na ang quintic ay hindi malulutas sa pamamagitan ng radicals at, bagaman Dalhin ay hindi claim na siya sa kanyang natuklasan na pagbabago sa pagtatangkang malutas ang quintic, ito ay malamang na ito ay sa katunayan kung bakit siya ay ang pagsusuri quintic equation.
