1. The problem statement, all variables and given/known data Doing my vector mechanics dynamics homework and I cannot believe I am stuck on this part. trying to factor t^3 - 6t^2-36t - 40 = 0 2. Relevant equations 3. The attempt at a solution I honestly do not remember where to begin. I remember there is a formula for perfect cubes, but do not remember what is needed for this situation. Any tips is greatly appreciated.
