Question 629913
<ul><li>The expression is not a function.</li><li>The expression is ambiguous. Is it
{{{x -1/x + 2}}}
or
{{{(x -1)/(x + 2)}}}
or
{{{x -1/(x + 2)}}}
or
{{{(x -1)/x + 2}}}?
Please use parentheses  to make your expressions clear. In order, the above should be posted as:
x -(1/x) + 2
or
(x -1)/(x + 2)
or
x -1/(x + 2)
or
(x -1)/x + 2</li></ul>
Please re-post the full problem in a clear way.
