C3 Quick Question

Just been doing this paper
http://www.mei.org.uk/files/papers/c305ju_dskjtr.pdf

Was wondering how you do Q8 i)

Curve y = xsin3x crosses x axis at P.
Find the x co-ordinate of P.

So I made it = 0
Then I had no idea what to do next!

Its probably ridiculously simple but I can't work it out from the mark scheme.
Help would be much appreciated :smile:
