Morphology

quadratic + equation

This term is fully compositional: 'quadratic' denotes 'second-degree' (related to a square) and 'equation' is a mathematical sentence, so a quadratic equation is simply an equation of second degree (e.g. ax²+bx+c=0). The mathematical naming pattern is regular and cross-linguistically familiar, so a learner who knows both constituents can infer the meaning.

Etymology

Quadratic equation comes from a word meaning 'square'. Quadratic points to x squared, which is x times x, and equation means a statement where two things are equal, so quadratic equation means 'an equation where the unknown is squared'.
