# SEBA CLASS 10 MATHS CHAPTER 4 MCQ  QUADRATIC EQUATION

3 Questions of 1 mark each will come from SEBA Class 10 Maths Chapter 4 MCQ (Quadratic Equations). Quadratic Equation is an important chapter not only in Class 10 but it has immense application afterwards.

So, we have prepared 10 important MCQ Questions from SEBA Class 10 Maths Chapter 4 Quadratic Equation. Before that, we will provide a detailed syllabus and topics of Quadratic Equation prescribed by SEBA for Class 10. Moreover, we have provided mark distribution of SEBA Class 10 Chapter 4 Quadratic Equation.

## SYLLABUS OF SEBA CLASS 10 MATHS CHAPTER 4 (QUADRATIC EQUATIONS)

First let us know the syllabus of SEBA Class 10 Maths Chapter 4 – Quadratic Equations.

• Standard form of a quadratic equation ax2 + bx + c = 0, (a ≠ 0).
• Solutions of quadratic equations (only real roots) by factorization, and by using quadratic formula.
• Relationship between discriminant and nature of roots.
• Situational problems based on quadratic equations related to day to day activities to be incorporated.

## TOPICS COVERED UNDER SEBA CLASS 10 MATHS CHAPTER 4 (QUADRATIC EQUATIONS)

The SCERT Maths textbook for Class 10 has the following topics in Chapter 4 – Quadratic Equations.

• 4.1 Introduction
• 4.3 Solution of a Quadratic Equation by Factorization
• 4.4 Solution of a Quadratic Equation by Completing the Square
• 4.5 Nature of Roots

There are 4 exercises covering the above topics. The solution of Chapter 4 exercises can be found in this link.

## SEBA CLASS 10 MATHS CHAPTER 4 (QUADRATIC EQUATIONS)

A quadratic equation is a type of polynomial equation of degree 2. The standard question of an quadratic equation that can be written in the form:

ax2 + bx + c = 0

where a, b, and c are constants and x is a variable.

Quadratic equations can have zero, one, or two solutions, depending on the values of the constants a, b, and c.

x = (-b +/- sqrt(b2 – 4ac)) / (2a)

where sqrt(b2 – 4ac) is the square root of (b2 – 4ac).

For example, to solve the quadratic equation x2 + 4x + 3 = 0, you would plug the values a=1, b=4, and c=3 into the quadratic formula:

x = (-4 +/- sqrt(42 – 4*1*3)) / (2*1)

x = (-4 +/- sqrt(16 – 12)) / 2

x = (-4 +/- sqrt(4)) / 2

x = (-4 +/- 2) / 2

x = -3 or x = -1

So, the solutions to the equation x2 + 4x + 3 = 0 are x = -3 and x = -1.
