polynom package gives the following!
- The first mark : I'd like to remove the space between the parenthesis and the overline as marked.
- Next two marks : I'd like to write x³+2x² instead of -x³-2x². That is, I'd like to put the product of the divisor and the quotient without multiplying by a negative sign.
- If possible, I'd like to have faint zero co-efficient terms as shown below.
I'd like to get the result as follows. A parenthesis can be used instead of the vertical stroke between the divisor and the dividend.
