Right now this question should be easy but i am unsure as to what it is exactly asking for, I know how to complete the square but how should i display my answer, please help!

By completing the square, or by quoting the known facts in relation to a quadratic function, show that for all x E R


F(x) = -3x^2 + 6x -9 < -6

This is a completing the square question not differentiation one. Thanks any how though.

Well, says who? I appreciate if it's under a "completing the square" heading, then I suppose you ought to do it that way, but in any moderately decent exam or project then any valid method will be accepted.

chill out.
