Given xpower2-x-6
   therefore  xpower2-3x+2x-6=0
                 x(x-3)+2(x-3)=0
                (x-3)(x+2)=0
   therefore(x-3)=0 (or)(x+2)=0
         that is   X=3 or x=-2
Sum of the zeros=3+(-2)=1= -(coefficent of x) / coefficent of x power2)
product of zeroes=3*-2=-6= (constant) / (coefficent of xpower2)
