[Maxima] how to show the "greek word" in maxima, how to show the (a+b)^2 by human sense

[=?big5?B?tsAguM62rw==?=]

Dear Adam
       1. how to show the greek word such as "alpha", "beta" , "gemma" in maxima
        2. how to show the formula by human sense
 in maxima , that is
(%i4) expand((a+b)^2)
(%o4) b^2+2*a*b+a^2

how can I let the answer of expand((a+b)^2) is
         a^2+2*a*b+b^2
