1. The problem statement, all variables and given/known data Find all zeroes for the function f(x) f(x)=x^3+25x 2. Relevant equations 3. The attempt at a solution I tried factoring out x out of it. x(x^2+25) and again to give x[(x+5i)(x-5i)] this would give me the 0,-5i,+5i as the zeroes. Doesn't seem to be right though. Any thoughts? Thanks!
