I replied to Bernadette privately before seeing this.

\* is a standard TeX macro that denotes an implicit multiplication and
serves as an hyphenation. It is either ignored or expanded to × when line
breaking occurs.

Any reasonnable (La)TeX processor will handle it, and this improves the
display when very large polynomial are printed.
