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) = a0 + a1x + a2x2 + a3x3 + … + anxn is called a polynomial,
where a0,a1,a2,a3,..an 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 ax4 + bx3 + cx2 + dx + e and a is not equal to 0.
