Chapter4- Quadratic Equation

Comprehensive Study of the Chapter Quadratic Equation!

In maths, the quadratic equation is a polynomial equation which can be written in the following form: ax2+bx+c = 0, where x refers to a variable and a, b, c are constants and ‘a’ cannot be zero. The constants a, b, and c are called respectively the quadratic coefficient, the linear coefficient, and the constant term.

ScoreX™ has brought up a significant change in the way of learning. Now, you can learn quadratic equations more quickly and effectively.

What is the format of this course?

In this course, we not only cover the important topics but also the NCERT Solutions CBSE Class 10 Maths Chapter 4 for your efficient learning.

1.  What do you mean by Quadratic and Roots?

It is a polynomial of degree 2. The term ‘quad’ means square as the variable gets the power of two like x2 whereas a real number ‘a’ is called a root of the quadratic equation, and they are also called zeroes of the polynomial.

2.  What are the forms of Quadratic function?

There are basically three types of forms named as General form, Vertex form, and Factored form. The general form is the most common one and the other two are used specifically. Vertex form is used in graphs and factored form includes a use of roots.

3.  What is Discriminant?

The expression of b2-4ac is called discriminant as it discriminates among the possible types of answer. It is denoted by D.
