Answer 1

`-k^2+7k`

Explanation:

Using the given equations, we must find
`C-B`

Start by substituting the given values into the expression:

`C-B\\k-3-(k^2-6k-3)`

Now, take the terms out of the parentheses.

`k-3-(k^2)-(-6k)-(-3)\\k-3-k^2+6k+3`

Please note that two negatives make a positive

`k-3-k^2+6k+3`
