1. Quadratic Equations

2. Solution by Factorisation

3. Solution by Completing the Square

4. Nature of Roots

**1.** The equation , is the standard form of a quadratic equation, where a, b and c are real numbers.

**Standard form **or **General form **of a quadratic equation.

In other words, we can say that an equation of order (degree) 2 is called a **quadratic equation**.

**2.** A real number is said to be a root of the quadratic equation , . If the zeroes of quadratic polynomial and the roots of the the quadratic equation are the same.

**3.** If we can factorise into product of two linear factors,then the roots of the quadratic equation can be found by equating each factors to zero.

**4.** The roots of a quadratic equation , are given by provided that . It is called **Quadratic formula**.

**5.** A quadratic equation , has :

(a) Two distinct and real roots, if

(b) Two equal and real roots, if

(c) Two roots are not real, if

**6.** A quadratic equation can also be solved by the method of completing the square.

(i)

(ii)

**7.** Discriminant of the quadratic equation , is given by .
