Can you please help me finding the vertex and intercepts for this equation, and whether it opens up or down?

I suppose the question is:
y= -3x^2 + 6x
In that case we have to factor -3 and complete the square:
-3x^2 + 6x= -3( x^2 - 2x)= -3(x^2 - 2x + 1 -1 )= ...
Vertex and intercepts are found and discussed. The solution is detailed and well presented.
