Def: An equation of unknown quantity (say x) in the form ax2+bx+c = 0 called a quadratic equation or a equation of the second degree , where a,b & c are constants whereas "X" is an variable.
Since, its a quadratic equation so The value of the co-efficient of "x2" can never be zero , i.e the constant "a" never be zero ,
but the other co-efficients can be zero i.e b & c can be zero.
