    The usual $x^2-2xy+y^2$ still applies.2011-04-19

    There is nothing to "solve". You have an expression, not an equation.2011-04-19

    Did you mean to have it equal to $0$?2011-04-19

    @Arturo Obviously the OP seeks to solve the problem of simplifying the expression. As a native (US) English speaker, I see no problem using the word solve in such a context.2011-04-19
