1. The problem statement, all variables and given/known data I am asked to solve the following equation, giving answer in terms of k 2. Relevant equations $$x^5 + k^2x = 0$$ 3. The attempt at a solution The answer is apparently 0. What is 0. Not even sure what that means. I would have thought: divide through by x to obtain $$k^2 = -x^4$$ → $$ k=x^2i $$ ???
