Vedclass · Answer

(B) quadratic equation is a polynomial equation of degree $2$. The standard form of a quadratic equation is $ax^2 + bx + c = 0$. For the equation to be quadratic,the coefficient of the $x^2$ term must not be zero. If $a = 0$,the equation becomes $bx + c = 0$,which is a linear equation,not a quadratic one. Therefore,the necessary condition is $a 
eq 0$.

The necessary condition for $ax^2 + bx + c = 0$,where $a, b, c \in R$,to be a quadratic equation is:
