Incomplete info. as it is x-x^2=max
how is the info incomplete?
a maximum: a maximum means nothing in of itself, a maximum to what?!

the maximum difference between any two real numbers
sorry the maximmum difference between any number and its square
for example for 0.8 the difference is .8 - .8^2 = .16
Ok, so we want to maximize \(f(x)=x-x^2\)
Without calculus: find the vertex \(x=-b/2a=-1/(2(-1))=1/2\). So it is maximum when \(x=1/2).
With calculus, set \(f'(x)=1-2x=0\). Hence \(x=1/2\). Then you just need to justify that x=1/2 gives the maximum value.
this is how i interpreted the question
right! how the heck didn't i think of that - ty. how do i give medals?
