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.
Solution (v)
Degree of Equation is 2. Therefore, it is a Quadratic Equation.
Solution (vi)
{
}
Degree of equation is 1. Therefore, it is not a Quadratic Equation.
Solution (vii)
{
}
Degree of Equation is 3. Therefore, it is not a quadratic Equation.
Solution (viii)
{
}
Degree of Equation is 2. Therefore, it is a Quadratic Equation.
