Morphology
The meaning 'a polynomial of the second degree' is directly and transparently derived from combining 'quadratic' (second-degree) with 'polynomial' (an algebraic expression of summed terms). This is a regular nominal composition found across languages and follows standard mathematical terminology, so a learner who knows both constituents can readily understand the MWE.
Etymology
Quadratic polynomial comes from the parts quadratic, meaning 'square', and polynomial, meaning 'many parts'. So a quadratic polynomial is a polynomial where the variable is 'squared' as x², which is why it is called 'second degree'.
