If p(x) is a polynomial in x, the highest power of x in p(x) is called the degree of the polynomial p(x).

A polynomial of degree 1 is called a linear polynomial.

A polynomial of degree 2 is called a quadratic polynomial. The name ‘quadratic’ to derived from the word ‘quadrate’ which means square.

A polynomial of degree 3 is called a cubic polynomial.

** Constant:** The value of constant remains same throughout in a particular situation i.e., the value of constant does not change in a problem.

** *** Variable:* A variable is a unknown quantity which is generally represented by an English alphabet like x,y,a,z etc,

** Polynomial:** A function p(x) of the from

p(x) = a_{0} + a_{1}x + a_{2}x^{2} + a_{3}x^{3} + … + a_{n}x^{n }is called a polynomial,

where a_{0},a_{1},a_{2},a_{3},..a_{n} are real numbers and are called coefficients of the polynomial and n is non-negative positive integer.

** Monomial: **A polynomial having one term is called monomial.

** Binomial: **A polynomial having two terms is called Binomial.

** Trinomial:** A polynomial having three terms is called a Trinomial.

** **** Biquadratic Polynomial: **A polynomial of degree four is called a Biquadratic Polynomial. it is represented as ax
