Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has two solutions. Among his many other talents, Major General Stanley in Gilbert and Sullivan's operetta the Pirates of Penzance impresses the pirates with his knowledge of quadratic equations in "The Major General's Song" as follows: "I am the very model of a modern Major-General, I've information vegetable, animal, and mineral, I know the kings of England, and I quote the fights historical, From Marathon to Waterloo, in order categorical; I'm very well acquainted too with matters mathematical, I understand equations, both the simple and quadratical, About binomial theorem I'm teeming with a lot o' news-- With many cheerful facts about the square of the hypotenuse." The roots can be found by completing the square, This equation is known as the quadratic formula. 325-270 BC) Data contains three problems involving quadratics. For example, for , there are four such polynomials, The following table summarizes the counts of such factorable polynomials for simple and small .
