    sir, but what method should I use to find the roots of the polynomial?

    eduncle-logo-app

    why you find the roots simply use the sum of roots and product of roots and you also know sum of roots is trace and product of roots is determinant so you get the answer if you have any queries then ask me if you got the point must consider my above answer. Thank you
