Mathematics for Standard X

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


Now observe the examples,  how to find zeroes of the Quadratic Polynomial 




The video of Types of Polynomial and how to factories the Quadratic Polynomial are available in following link
