Polinomiaj
Polinomiaj is a term that appears to be a misspelling or a neologism. In standard mathematical terminology, the concept referred to is likely "polynomial." A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. A polynomial can be written in the general form of $a_nx^n + a_{n-1}x^{n-1} + \dots + a_1x + a_0$, where $a_i$ are coefficients and $x$ is a variable. The highest exponent, $n$, is called the degree of the polynomial.
Polynomials are fundamental in algebra and are used to represent a wide variety of mathematical relationships.
