Question 296641
This quadratic equation has  2 real roots 0 and -121
Imaginary roots always come in pairs.
So b and d are out 
I have already shown two real roots so a is out
The only possible answer among the choices is c
but a quadratic (x^2) can have a maximum of 2 roots.
So none of the choices are correct. There must be a misprint in the choices or the problem.
