But you could notice that
Is it possible that ?
how exactly is that wrong though? It's how it factors isn't it?

- there is no solution (but x=3), so that's why you thought you were wrong
- you forgot a situation : -x+3<0 and x-3<0 (their product is positive ). It'll also yield to an impossibility, but you mustn't forget this case.
So the final answer is just x=3? That makes sense.
hmmm amazing how a simple problem can trick me even when my working is correct
