## Historical Note on Quartic Equation

The solution of the **quartic equation** followed soon after the solution of the cubic.

It was included in Gerolamo Cardano's *Artis Magnae, Sive de Regulis Algebraicis* of $1545$, along with his solution of the cubic, which had been solved some few decades earlier by Scipione del Ferro.

It was solved by Lodovico Ferrari, who was a student of Cardano's.
