How can you further simplify this: s(s-a)(s-b)(s-c)?

To further simplify the expression s(s-a)(s-b)(s-c), you can expand it by multiplying the terms together:

s(s-a)(s-b)(s-c) = s(s^3 - s^2b - s^2c + sab - sb^2 + abc)

This is the most simplified form of the expression.

s(s-a)(s-b)(s-c) = s(s^3 - a s^2 - bs^2 + abc)
= s^4 - as^3 - bs^3 + abcs
= s^4 - (a+b)s^3 + abcs
