**1. Check whether the following are Quadratic Equations**

(i)

(ii)

(iii)

(iv)

(v)

(vi)

(vii)

(viii)

We just check degree of equation. If, degree of equation is equal to 2 then only it is a **quadratic equation**.

**Solution (i)**

{}

**Degree of equation is 2. Therefore, it is a Quadratic Equation.**

**Solution (ii) **

**Degree of equation is 2. Therefore, it is a Quadratic Equation.**

**Solution (iii) **

**Degree of equation is 1. Therefore, it is not a Quadratic Equation.**

**Solution (iv) **

**Degree of equation is 2. Therefore, it is a quadratic equation.**

**So****lution (v) **

**Degree of Equation is 2. Therefore, it is a Quadratic Equation.**

**So****lution (vi) **

{}

**Degree of equation is 1. Therefore, it is not a Quadratic Equation.**

**So****lution (vii) **

{}

**Degree of Equation is 3. Therefore, it is not a quadratic Equation.**

**So****lution (viii) **

{}

**Degree of Equation is 2. Therefore, it is a Quadratic Equation.**
