Question

Simplify $x(x+6)=0$ and check whether it is a quadratic equation.

Answer 1

We know that the general form of quadratic equation is $a{x}^2+bx+c=0$.

The given equation is $x(x+6)=0$ can be simplified as follows:

$x(x+6)=0\Rightarrow x^2+6x=0$

Since the equation $x^2+6x=0$ is of the form $a{x}^2+bx+c=0$.

Hence, the equation $x(x+6)=0$ is a quadratic equation.
