Of course, the polynomial at issue in the proof is much more complicated than that.Tetrahedron Solutions Finally Proved Decades After Computer Search|Kevin Hartnett|February 2, 2021|Quanta Magazine
To solve those in a similar way, Wolfson thought, you could replace that cubic surface with some higher-dimensional “hypersurface” formed by those higher-degree polynomials in many variables.
In July, three computer scientists used a mathematical discipline called the geometry of polynomials to show that a modern algorithm is guaranteed to be at least infinitesimally more efficient than the long-standing best method.
The only multilinear maps researchers knew how to build securely were those that computed polynomials of degree 2 or less.Computer Scientists Achieve ‘Crown Jewel’ of Cryptography|Erica Klarreich|November 10, 2020|Quanta Magazine

The two dots at the end are frequently omitted when the part affected includes all the terms of the polynomial to the end.William Oughtred|Florian Cajori
It was natural to inquire whether a similar theorem holds for integrals ∫R(s, z)dz wherein s is a cubic polynomial in z.
The last case arises when we consider the finite values of z for which the polynomial coefficient of sn vanishes.
But the polynomial method as a system was of short duration.
This polynomial expression was shortened by Linnæus to Zeus faber.
British Dictionary definitions for polynomial
- a mathematical expression consisting of a sum of terms each of which is the product of a constant and one or more variables raised to a positive or zero integral power. For one variable, x, the general form is given by: a 0 x n + a 1 x n –1 + … + a n –1 x + a n, where a 0, a 1, etc, are real numbers
- Also called: multinomial any mathematical expression consisting of the sum of a number of terms
