Question 719123
Please put parentheses around numerators and denominators. What you posted (without parentheses) means:
{{{z^2-4/z-3 / z+2/z^2+z-12}}}
But I'm pretty sure this is not what you intended. I can't even guess what you did intend because there are too many possible numerators and denominators in the expression you posted.<br>
You are more likely to get a quick response when your post is clear and unambiguous. Please re-post your question using parentheses.
