Which of the following are quadratic equations?

$x^2\ -\ 3x\ =\ 0$

Given:

Given equation is $x^2\ -\ 3x\ =\ 0$.

To do:

We have to check whether the given equation is quadratic.

Solution:

The standard form of a quadratic equation is $ax^2+bx+c=0$.

$x^2\ -\ 3x\ =\ 0$

$x^2\ -\ 3x\ =\ 0$ is of the form $ax^2+bx+c=0$ where $a=1, b=-3$ and $c=0$.

Therefore,  $x^2\ -\ 3x\ =\ 0$ is a quadratic equation.
