RD Sharma Class 10 Chapter 8 (Quadratic Equations) Solutions

In this chapter, you will find a variety of questions to solve from the exam point of view. While NCERT Class 10 textbook questions are straightforward, questions of RD Sharma Class 10 Chapter-8 are twisted and require more practice. Having knowledge of previous two chapters will help you understand the concepts in a better manner. 

Important Formulas| RD Sharma Class 10 Chapter-8

x = (-b ± √b² - 4ac)/ 2a, given that b² - 4ac ≥ 0

2. When you solve a quadratic equation ax² + bx + c = 0, you may obtain one of the three results mentioned below.

(a). Two different real roots, if b² - 4ac > 0

(b). Two roots having same values, if b² - 4ac = 0

(c). No real roots, in case you obtain b² - 4ac < 0
