1. If (x-2)(x-4)=7 then students write (x-2)=7 or (x-4)=7 as they do in case of (x-2)(x-4)=0 means either (x-2)=0 or (x-4)=0
2. While writing the value of 2x^2 at x=5, students write 25^2
3. They forget to take the negative sign of coefficient of x in x^2-5x+7
4. zero of a polynomial is misunderstood as 0 whereas zero of a polynomial can be any real number
