Probably, but it is difficult to be certain because limitations of the browser used by Answers.com means that we cannot see most symbols.

If the question was about x3 - 8x + 7 then a definite yes.

But if not, please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
