Check whether the following are quadratic equations:

2 x^{2} - 3 x + 5 = 0

Solution:

Given,

2 x^{2} - 3 x + 5 = 0

\Rightarrow 2 x^{2} + 5 = 3 x

\Rightarrow (2 x^{2} + 5)^{2} = (3 x)^{2}

\Rightarrow 4 x^{4} + 20 x^{2} + 25 = 9 x

\Rightarrow 4 x^{2} + 20 x^{2} - 9 x + 25 = 0

∵

The highest power of x in the equation is 4;

∴

It is not a quadratic equation.
