He had been working again on the algebraic solution of equations, with the aim of solving the problem of which equations were soluble by radicals (the problem which Galois solved a few years later).
Niya ay nagtatrabaho muli sa algebraic solusyon ng equation, na may layunin ng nilulutas ang problema ng mga equation na kung saan ay maaaring malutas sa pamamagitan ng radicals (ang problema na Galois malulutas ng ilang mga taon mamaya).
