Simplify. Write your answer using whole numbers and variables.
s–7
s2–7s

The simplified expression is s + (-7) and s^2 - 7s.

1. The expression s-7 cannot be simplified any further since there is no like term to combine with the variable s.

2. The expression s^2-7s can be simplified by factoring out the common factor of s. We can rewrite it as s(s-7).

To simplify the expressions s-7 and s^2-7s, we need to combine like terms.

For the expression s-7, there are no like terms to combine as s and 7 are different. Hence, it remains as s-7.

For the expression s^2-7s, we can factor out the common term s:

s^2 - 7s = s(s-7)

So the simplified form of s^2-7s is s(s-7).

In summary:
- The expression s-7 remains unchanged.
- The expression s^2-7s can be simplified to s(s-7).
