1. The problem statement, all variables and given/known data It's asking me to find all the real and complex zeros of the function x^3 + 2x^2 - 16. 2. Relevant equations 3. The attempt at a solution I have tried factoring the first 2 terms and i come up with x2(x+2) - 16 but I don't know where to go from there. Any help would be appreciated.
