Question
$m^3+3 m^2-2=3 m^3$
✓
Answer
$m^3+3 m^2-2=3 m^3$
$\Rightarrow m^3+3 m^2-2-3 m^3=0 \Rightarrow-2 m^3+3 m^2-2=0$
$\therefore$ it is not a quadratic equation because it is not in the form of $ax ^2+ bc + c =0$
$\Rightarrow m^3+3 m^2-2-3 m^3=0 \Rightarrow-2 m^3+3 m^2-2=0$
$\therefore$ it is not a quadratic equation because it is not in the form of $ax ^2+ bc + c =0$
