they have variable
Adding and subtracting polynomials is simply the adding and subtracting of their like terms.
The sum of two polynomials is always a polynomial. Therefore, it follows that the sum of more than two polynomials is also a polynomial.
division
A "non-polynomial" can be just about anything; how alike they are depends what function (or non-function) you specifically have in mind.
Binomials and trinomials are two types of polynomials. The first has two terms and the second has three.
2x² − 7x + 5
Exponential, trigonometric, algebraic fractions, inverse etc are all examples.
Other polynomials of the same, or lower, order.
they have variable
Reducible polynomials.

In mathematics, Jacobi polynomials (occasionally called hypergeometric polynomials) are a class of classical orthogonal polynomials.
what is the prosses to multiply polynomials
Descartes did not invent polynomials.
