    it seems it's an application of the rational roots theorem and factor theorem...

    1. Find one of the factors (maybe use rational roots theorem) 2. Divide the polynomial by that factor (the quotient will be a quadratic equation) 3. Factor out that quadratic equation (maybe using quadratic formula) that's how i do it...

    these are actually a part of a big ques... so it ought to be solved to solve the big prob!
