That's easy. You can't "solve" it. You might be able to simplify it, and I emphasize might. But solving something requires that there be a relationship operator somewhere in your expression, that is either an equals sign or one of the four possible inequality signs.
Also, you need to use parentheses to indicate which parts of your expression are in the numerator and which parts are not part of the indicated rational expression.
Don't write back to me because I might not be able to get to your question for a day or two. Re-post with the correct information.
