How do I do solution to (b)?

[bright flint]

The answer is apparently (p-q)(q-r)(r-p)(pq+qr+rp+p^2+q^2+r^2), but I keep getting the answer in negatives (I mean -(p-q)(q-r)(r-p)(pq+qr+rp+p^2+q^2+r^2), btw.). How do I do this?

2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
3. Do not ping other members randomly for help.
4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.

You probably messed up the signage in your working. As stated before, show your work so we can identify the error.

You can also just look at signs of certain terms to double check.

Use wolfram alpha to verify your ans

Does it perform well?
I doubt it actually.
From my observation ChatGPT reasoning (o4 or sth) performs better

But anyway. For this math problem any software capbable of math is OK
