### Theory:

*Polynomials*

A polynomial is an expression consisting of variables and constants which involves four fundamental arithmetic operations \((\)\(+\), \(-\), \(\times\), \(\div\)\()\) and non-negative integer exponents of variables.

Example:

*Classification of polynomials*

*Zero of a polynomial or Root of a polynomial*

If \(p(x)\) is any polynomial and \(x = a\) is said to be the root or zero of a polynomial if \(p(a) = 0\).

Also, if \(p(a) = 0\) then \(a\) is said to be the root of the polynomial equation \(p(x) = 0\).
