This exercise (Solving quadratics by factoring) only expects one answer, so the next to last hint gives the correct answer:
"Thus, x = 1 is the solution."

The last hint gives two answers so it is probably meant for the next exercise (Solving quadratics by factoring 2)
"Thus, x = 1 and x = -4 are the solutions."

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.

Ben, my Simplifying Square Roots of Negative Numbers and other minor fixes got accidentally pulled in with this fix by me (new to Git). Perhaps you have included it on purpose.
Also, Solving Quadratics by Factoring 2 needs the same fix too. #33388
