I have a semantics question.

Why is the quadratic equation called what it is?

A polynomial of degree two is called a quadratic polymonial but I've always associated the root quad to mean four!!

Thanks in advance.

It notes that "quadratic" is from the Latin for "to make square" or, as Lamoid said, simple "square". Of course, a square has four sides which is where your use of the word is from.
