Answer:
-p^2-(q+r)^2

Work Shown:

I'm assuming your teacher wants you to factor as much as possible.


-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\

In the last step, I used the rule that
(a+b)^2 = a^2+2ab+b^2

We cannot factor any further. If the first term was
p^2 instead of
-p^2, then we could use the difference of squares factoring rule.
