Chapter no.2 Polynomials
Today we are going to learn Polynomials, Types of Polynomial and how to find out the zeroes of the Polynomial .
In class IX , you have studied Polynomials in one variable and their degrees.
Polynomial :- A Polynomial is an expression consisting of variables and coefficients that involves , only the Operations of addition, subtraction, multiplication and non-negative integer exponents of variables.
e.g 2x + 3 , 5y etc.
The degree of the Polynomial : - The highest power of variable in Polynomial is called the degree of the Polynomial.
Types of Polynomial :- According to degree, the Polynomials are classified as given below.
1) Linear Polynomial : - A Polynomial of degree 1 is called a linear polynomial.
e.g 4y + 5 , 6x etc
2) Quadratic Polynomial :- A Polynomial of degree 2 is called quadratic polynomial .
e.g x square - 5 , y square + 7y + 12 etc.
3) Cubic Polynomial :- A Polynomial of degree 3 is called cubic polynomial .
e.g x cube - 8 , x cube + 4 x square + 5x -20 etc.
Exercise 2.1
