(B) Given equation: $9x = 3x^3$.Rearranging the terms to one side,we get: $3x^3 - 9x = 0$.$A$ quadratic equation is defined as an equation of the form $ax^2 + bx + c = 0$,where $a 
eq 0$ and the highest power (degree) of the variable is $2$.In the equation $3x^3 - 9x = 0$,the highest power of the variable $x$ is $3$.Since the degree of the polynomial is $3$,it is a cubic equation,not a quadratic equation.Therefore,$9x = 3x^3$ is not a quadratic equation.

Examine whether the following equation is quadratic or not: $9x = 3x^3$.
