Please help for when a limit doesn't exist

Ok this is the problem:

Find the limit as x approaches zero

0^3 +x/x

Ok.. so I know it's zero over zero so it's undefined but how can I further

distribute the problem ? I remember my professor saying that we could take a step further but I don't know how to do it in this case.

Hopefully this is enough information to get MUCH needed help

When a limit doesn't exist

it's #2 on your reply. And once I plugged the zero into the equation I got 0/0. In a similar problem done in class our professor further simplfied the answer by distributing the orignal function then cancelling out the like terms from the denominator. But I am somewhat fuzzy on the rest and don't know how to further simplify the answer. (Worried)
