Answer 1

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.
