Does Wolfram care Shanon functions?

I totally do not adjust Mathematics look like very rude formula and definition.
then I am very expecting Wolfram alpha to understand formula easily.
When I facing many formula(or something written by a or b or x etc..)  , actually I have no idea which is formula or function even if graphical or algebra but I have to explain something about these lines.

still does not google like..

So I tough I can blow all bunch of formula or something that is not liter-actual line into Wolfram but still it has no idea

y=-(x(log2(x)))-((1-x)log2(1-x))
