Wrong extra hint on end of solving quads by fact.

```Fixes Open #33388 #33076 #33077 Closed #31645 #29435 #30472 #30400

Solving quadratics by factoring (& 2) added and extra hint for the
one-root problem.  Both used appendContents but recently multiple
problem had one more hint than one-root problem added.  Kept the new
text, but merged the new hint with old.```
