Class 10 Maths Chapter 4 Quadratic Equations Important Questions in Hindi Medium with solutions for board exam 2024-25. Chapter 4 of the Class 10 Mathematics curriculum Quadratic Equations is a pivotal part of algebra that builds upon the foundational concepts learned in previous classes. The chapter 4 delves into the detailed study of quadratic equations, which are integral in various fields like physics, engineering, and economics.

Class 10 Maths Chapter 4 Quadratic Equations Important Questions

Class 10 Maths chapter 4 important questions introduces the concept of a quadratic equation at board exam level.

It is defined as an equation of the second degree, generally represented in the form ax² + bx + c = 0, where a, b, and c are real numbers, and a ≠ 0.

The extra questions of chapter 4 in 10th Maths explain the standard form of a quadratic equation and the significance of its coefficients and constant term.

The chapter 4 begins with a discussion on the nature of quadratic equations, illustrating how they are different from linear equations and the unique characteristics they possess, such as the possibility of having two solutions.

Finding the roots of a quadratic equation

In the chapter 4 we learn about the methods of finding the roots of a quadratic equation. The most common methods include factorization, completing the square, and using the quadratic formula, which is derived in the chapter. Factorization involves expressing the quadratic equation as a product of two linear factors.

Completing the square is a method where the equation is transformed into a perfect square expression, making it easier to solve.

The quadratic formula, derived from the process of completing the square, provides a direct method to find the roots of any quadratic equation. This topic is important as it equips students with various techniques to solve quadratic equations.

The nature of the roots of quadratic equations

The chapter 4 also focuses on the nature of the roots of quadratic equations. It delves into the discriminant (usually represented as D or Δ), which is part of the quadratic formula and determines the nature of the roots.

The chapter 4 explains how the value of the discriminant can indicate whether the roots of a quadratic equation are real and distinct, real and equal, or complex. Here is a way to understand how the coefficients of a quadratic equation influence its roots and how to predict the nature of these roots without actually solving the equation.

In class 10 Maths chapter 4 student will learn about the relationship between the roots and coefficients of a quadratic equation. It explains that the sum and product of the roots of a quadratic equation can be determined from its coefficients.

This concept is known as Vieta’s formulas. The chapter 4 quadratic equations also explores how these relationships can be used in reverse to construct a quadratic equation when the roots are known.

This is one of the important chapters for students to understand the symmetrical properties of quadratic equations and how roots and coefficients are interdependent.
