1. The problem statement, all variables and given/known data Actually, it is told by one of my friend. He asked for the answer of this quadratic equation. m^3-m^2+2=0 2. Relevant equations m^3-m^2+2=0 3. The attempt at a solution But, I think we need one more equation to solve it. Is there any way to solve it by only one equation? If yes, please describe it or if not, then tell me the proper reason..
