2.0CBSE Class 10 Maths Chapter 2 Polynomials - Revision Notes

This chapter introduces the idea of polynomials. Expressions that contain exponents, constants, and variables are called polynomials. In algebra, it is a crucial issue. The following lists some of the key ideas that lie under the umbrella of "polynomials":

Important Concepts in Polynomials

Definition of Polynomials: Expressions that include variables with non-negative integer exponents, such as

  1. Types of Polynomials
  • Constant Polynomial: Contains no variables, only a constant (e.g., 5, 7, 10).
  • Linear Polynomial: Has a variable raised to the power of 1 (e.g., x + 2 or 3x + 5).
  • Quadratic Polynomial: Contains a variable raised to the power of 2 (e.g. ).
  • Cubic Polynomial: Contains a variable raised to the power of 3 ().
  • Zeros of a Polynomial: The values of the variable that make the polynomial equal to zero. For example, in x2 − 4, the zeros are x = 2 and x = −2.
  1. Definitions:
  • Degree of a Polynomial: The highest power of the variable in a polynomial. For example, x3 + 3x + 1 has a degree of 3.
  • Monomial, Binomial, and Trinomial: These refer to polynomials with one, two, and three terms, respectively, like 3x (monomial), x + 1 (binomial), and x2 + 2x + 1 (trinomial).
  1. Formulas:
  • Standard Form of a Quadratic Polynomial: , where a, b, and c are constants.
  • Finding Zeros of a Polynomial: For a quadratic polynomial , the zeros can be found using the formula.

  • Relationship between Zeros and Coefficients:

 For ax2 +  bx + c: Sum of zeros =

Product of zeros =

  1. Tips & Tricks:
  • Remember Polynomial Degrees: Constant (0), Linear (1), Quadratic (2), and Cubic (3).
  • Using the Factor Theorem: This can help to quickly verify if a given value is a zero of a polynomial by substituting it into the polynomial equation.
  • Using Graphs for Visual Understanding: Plotting polynomials can help in understanding the nature of roots (real or imaginary) and the shape of the curve.

3.0Key Features of CBSE Maths Notes for Class 10 Chapter 2

  • Exam-Focused Content: These are useful revision notes since they include important exam-related formulae, properties, and theorems that assist pupils in concentrating on scoring portions.
  • Solved Examples for Better Understanding: These revision notes are helpful since they include solved examples along with detailed answers, which will assist the learner in comprehending how polynomial issues may be solved.
  • Formula Tables for Quick Reference: Being in easy-to-read table format, these key formulas would be useful in finding the sum and product of zeroes, polynomial identities, and algorithms on division are very helpful towards making last-minute revision much more efficient.
  • Simple Language and Illustrations: Simple, everyday language is used to explain concepts, and images are used to aid in explaining more complicated ideas, such as polynomial graphing.
  • Visual Aids and Graphical Representations: To help comprehend the nature of roots and how they affect the structure of the polynomial graph, graphs and other visual aids are used to show how polynomial functions behave. This is especially beneficial for those who learn best visually.
  • Aligned with CBSE Syllabus: The notes are created to meet CBSE standards, ensuring that all important topics in Chapter 2 are covered comprehensively.
