In general: $\int_2^4 \frac{f(x)}{f(x)+f(6-x)}\,dx=1$.

@JavaMan Not necessarily "opening downwards" -- if $a<0$.

comment How can I solve this system?
Plugging the 1st and 2nd equations into the 3rd, we get a quadratic equation for y.

comment How could we find the largest number in the sequence $ \sqrt{50},2\sqrt{49},3\sqrt{48},\cdots 49\sqrt{2},50$?
Note that if the original question is for example $n\sqrt{50-n}$ instead of $n\sqrt{51-n}$, no integer $n$ satisfies the equality of the AM-GM inequality; in that case, a more careful evaluation, such as that used in Jyrki Lahtonen's answer, is needed.
