quadratic

[tony873004]

A 3rd degree polynomial is called a cubic, and a 2nd degree is a quadratic. But quad implies 4. Why is a 2nd degree called quadratic?

[[Quadratic]]

The word comes from the Latin word quadratus, meaning "square". Quadratic functions deal with calculating the area of squares.
