In the x^2/x = x, what would happen if x = 0?

I am probably forgetting or missing something very simple thanks to being years passed to my math education. But this confuses me.

Because of the obvious you can't divide by 0.

An equation is only valid as long as both sides are actually defined. So this equation only holds for x non-zero, because if x=0 the left-hand side is not defined.

If you ever have learned about limits, you do maybe recall that one possibility to interpret your question differently is: what is the limit of x^2 /x as x->0? The answer 0. This does however in no way say that x^2 /x is defined at x=0.
