Answer 1

[AI-generated answer — Bot GPT 3.5]

To divide (n^2 - 3n - 21) by (n - 7), we can use polynomial long division or synthetic division.

Using polynomial long division:

n + 4
_______________
n - 7 | n^2 - 3n - 21
- (n^2 - 7n)
____________
4n - 21
- (4n - 28)
__________
7

Therefore, (n^2 - 3n - 21) divided by (n - 7) is equal to n + 4 with a remainder of 7.
