In general, to solve math problems you need some logical reasoning, not just formulae. If you solve a physics problem with a math formula and it gives you two answer - for example, a negative and a positive answer - you should check each one, whether it makes sense in the context of the problem. In some cases, negative answers don't make sense; in others, they do. Note that there may very well be problems that have more than one possible answer.
