American Journal of Mathernagics, vol. xxiii. No. 3.—Geometry on the cubic scroll of the second kind, by F. C. Ferry, is the conclusion (34 pp.) of a paper commenced in the last number ...

Unlike quadratic, cubic, and quartic polynomials, the general quintic cannot be solved algebraically in terms of a finite number of additions, subtractions, multiplications, divisions, and root ...

Both the cubic and the quartic equations were finally solved in the 1540s by Gerolamo Cardano and Ludovico Ferrari, ... Clearly, the quintic was next, but progress was remarkably slow.

Although he began as Cardano’s servant, Ferrari eventually became Cardano’s mathematical equal. By helping Cardano with his work on the cubic, he became so algebraically adept that he discovered how ...
