CBSE Notes for Class 10 Maths Chapter 4 - Quadratic Equation


NCERT Solutions for Class 10 Maths: Quadratic equations for Class 10 Maths: Learn everything you need to know right here. For the 2022-23 CBSE Board Exams, these quadratic equations notes will assist students to remember the definitions, formulas, and strategies needed to answer the problems. There are many examples in this article to help you understand the concept of quadratic equations and how to find the solution for given quadratic equations. 

Despite its allure, mathematics is a difficult subject to master because of the time and effort it requires. In order to prepare better for the first and second terms of the class 10, students can use the NCERT Solutions Class 10 as a study aid. Students can solve the activities and identify their weak points in a chapter after completing a single chapter. Prior to the exam, they might focus on and strengthen their weak points.

Standard form of Quadratic Equation

The standard form of a quadratic equation is ax2+bx+c=0, where all the variables like a, b and c are real numbers and a≠0. In this equation ‘a’ is the coefficient of x2 and it is also known as quadratic coefficient.  The variable ‘b’ is the coefficient of x. It is called the linear coefficient. Lastly, ‘c’ is the constant term.


b2-4ac is the discriminant (D) of the quadratic equation, which can be utilized to solve the quadratic equation. The discriminant roots of a quadratic equation are determined by its coefficients. 

Weightage of Chapter 4 Quadratic Equations:

Only if students practice the greatest number of problems, analyze themselves, and keep working on their weaknesses until the exam comes will they be able to get good scores from this chapter's 7-8-point questions.

Nature of Roots

Quadratic equation roots can take one of three forms depending on the discriminant, D=b24ac.

Case 1: If D>0, the equation has two distinct real roots.

Case 2: If D=0, the equation has two equal real roots.

Case 3: If D<0, the equation has no real roots.



Nature of the graph for various D values.

If D > 0, the parabola crosses the x-axis exactly twice. The rhizomes may be easily distinguished from one another. In the given figure, the quadratic polynomial intersects the x-axis at two distinct points.

Even when D=0, only a very little piece of the curve rests on top of or below the x-axis. On the quadratic polynomial shown in the graphic above, there is only one point that crosses the x-axis.

When D<0, the parabola is totally above or below the x-axis, hence there is no point of contact. In this case, there are no actual roots.
