Sridharacharya derived the quadratic formula in A. D This chapter is crucial not only from an exam point of view but also to deal with various real-life situations. For instance, you can calculate the length and breadth of a hall using quadratic equations. You can form an equation based on the information that the hall has a carpet area of sq. In this chapter, you will learn more about quadratic equations and how to find their roots.
The Quadratic Equation Class 10 Notes for this chapter have been formulated by expert subject teachers to assist students with their overall preparation for the board exam. For this reason, the revision notes follow the NCERT guidelines to maintain accuracy and a high standard. The relevant sub-topics under this chapter have been highlighted in our Quadratic Equations Notes to help students go through them quickly while revising.
Key concepts and essential definitions come with an in-depth explanation to encourage better comprehension on your part. The revision notes are written in lucid language to boost your understanding and help you memorise them quickly.
Read through our revision notes to lend further clarity to your doubts and increase your chances of scoring high grades. Quadratic Equations Notes by us are divided into following sub-sections to help you revise efficiently before the examination. Under this section, you will learn to calculate the roots of quadratic equations. Here a, b and c are real numbers. It has been explained in our Quadratic Equations Notes with the help of an example.
As you go through our Quadratic Equations Notes, you will learn why this form of quadratic equations is called its standard form. Our revision notes will help you to revise how quadratic equations are used to represent real-life situations mathematically based on the information given in the question. Under this section from our Class 10 Maths Chapter 4 Notes, you will also learn how to find out the roots of quadratic equations using shortcut techniques.
While calculating the roots, you must remember that a root is a real number which satisfies the quadratic equation and is not equal to zero. Quadratic equations can be solved by applying more than one method. In this class, you will learn to factorise quadratic equations to find its roots. However, it would help if you kept in mind that to factorise quadratic polynomials, you must split the middle term.
You should also remember that to determine the roots; you must factorise the equation into linear factors and equate each factor to zero. After solving the quadratic equation and finding its roots, you must verify that these are the roots of the equation given.
You can go through our revision notes to review the method correctly. Since this is a very crucial method, you must practise it more than once and refer to our Quadratic Equations Notes to clarify your doubts, if any. You can even download our notes for Quadratic Equations Class 10 PDF and make it a part of your exam preparation process. Our notes contain a clear step by step explanation of the factorisation process, which you can easily memorise while revising a day before your board exams.
It is yet another method that can be used to solve a quadratic equation and find out its roots. Now you have to apply your knowledge of square and square roots to solve this equation. Hence, this method is known as the method of completing the square. The terms containing x is completely inside a square, and the roots were found by taking the square roots. This above method has been explained in our Quadratic Equations Notes with the help of an example.
Under this section, you can also recall your knowledge of the quadratic formula. This formula is used to calculate the roots of a quadratic equation.
Using this method, you can quickly solve a quadratic equation to find its roots. So revise this technique again and again to increase your accuracy and speed. Our Quadratic Equations Notes analyses this for your benefit.
You can quickly revise the following pointers by downloading our revision notes. A clear grasp of this will help you to understand the nature of the roots. Read through our Quadratic Equations Class 10 Notes which has been framed by expert maths teachers to strengthen your understanding of the basic concepts. That table is mentioned below. If the value of the discriminant is equal to 0.
The quadratic equation will have imaginary roots. Here, iq is the imaginary part of a complex number. The quadratic equation will have real roots. The quadratic equation will have natural roots. The quadratic equation will have irrational roots.
The quadratic equation will have integral roots. It is important to understand the relationship between the roots of quadratic equations and coefficients while going through Ch 4 Maths Class 10 Notes. This is why we will go through that exact topic right now.
This means that:. Keep all of these equations in mind. From these equations, it can be said that the relationship between the roots and coefficients of a polynomial equation can be derived if one simplifies the given polynomials and substitutes the results.
All of this can be depicted by the following equations:. By now, we have looked at almost all the major formulas and theorems related to quadratic equations in these notes of Chapter 4 Maths Class However, the one major topic that is still remaining is finding out the range of quadratic equations.
In this equation, a is not equal to 0. Also, a, b, and c are real. Hence, we can write the quadratic expression as:. Now, before moving forward, it is advised that you should look at the images that are given below. The first thing that you need to know about this image is that it shows the intervals in which the roots of a quadratic equation lie.
We will look at all of these cases below. Case 1: When both the roots of the quadratic equation are larger than any given number m. Case 3: If both the roots of a quadratic equation lie in a particular interval m 1 , m 2.
Case 4: This happens when one root of a quadratic equation lies exactly in the given interval Byjus Class 7 Maths Chapter 4 Jacket m 1 , m 2 and f m 1. Case 7: Both the roots of the quadratic equations are positive. Case 8: When both the roots of a quadratic equation are negative. Did you know that you 10th Class Maths All Formulas Pdf Free Download Pc can use quadratic equations to solve many problems in the real world? This is true as quadratic equations can help you solve problems related to speed and geometry. Many problems related to quadrilateral figures and problems related to distance and time can also be solved by using quadratic equations.
