**Quadratic Equations**

Here you will learn than an equation with the form a* x*2 + b

*+ c = 0, with*

*x**as the variable and a, b, c as real numbers (where a ≠ 0) is known as a quadratic equation. A quadratic equation is obtained upon equating the quadratic polynomial of the form a*

*x**2 + b*

*x**+ c, a ≠ 0 to zero. Some equations may be of higher degree and need to be simplified before deciding whether it is quadratic or not. We often come across quadratic equations in real-life situations.*

*x***Solving Quadratic Equation by Factorisation**

This part of the Chapter tells you that the first method of solving a quadratic equation is the factorisation method. Here values of the variable * x* are determined, for which a quadratic equation is satisfied. These particular values of

*are called the roots of the quadratic equation.*

*x***Solving Quadratic Equation by Completing the Square**

This section teaches you that a quadratic equation can also be solved by the method of completing the square like-

(* x* + a)2 – b2 = 0

**Nature of Roots**

This part of Cass 10 Maths Quadratic Equations teaches you that values of real roots vary for a quadratic equation of the form a* x*2 + b

*+ c = 0.vWhen b2 – 4ac > 0, then the equation possesses two distinct real roots. In case b2 – 4ac = 0, then the equation has two equal roots.*
