Quadratic Equations

A quadratic equation in $x$ is $ax_{2}+bx+c=0$, where $a,b,c$ are real numbers and the other condition is

- $a=0$
- $b=0$
- $c=0$
- $b=0$

As $x$ is raised to power $2$ it is a quadratic equation.

If $a=0$, then it will nullify $x_{2}$, making it a linear equation.

So only if $a=0$, the equation remains quadratic.

Option A is correct.
