Can you find the values of X for which the above expression is hint: Write it as a quadratic then find the solutions that give exactly 0. Then plot the graph and the range of values is clear Spoiler: http://www.wolframalpha.com/input/?i=%28x-3%29^2+-+3x+%2B9+%3C%3D+0
Got it, thank you.

whoops... disregard. I misinterpreted the original question... My bad
