A polynomial expression is a mathematical expression consisting of constants and variables, combined with the operations of addition and multiplication.
A polynomial expression is of the form:-
[tex]ax^{2}+bx+c[/tex]
Here, it consists of variable x, constants a, b and c and operations + and *.
Hence, it is a polynomial expression.
This particular polynomial expression is a quadratic expression.
Other examples of polynomial expressions are :-
5x + 3, [tex]4x^{3}+3x^{2}}+2x+1[/tex] ,2x + 3y = 4 and so on.
A general polynomial expression can be written as:-
[tex]a_{n}x^{n}+a_{n-1}x^{n-1}+a_{n-2}x^{n-2} + ......+ a_{1}x^{1}+a_{0}[/tex]
It has (n + 1) terms, with variable x, (n + 1) constants and operations + and *.
