Warm Up

Your teacher will assign you one of these expressions:

$\frac{n^{2} - 9}{2 (4 - 3)} or (n + 3) \cdot \frac{n - 3}{8 - 3 \cdot 2}$

For questions 1 – 4, evaluate your expression when $n$ is the given value.

$n = 5$

$n = 7$

$n = 13$

$n = - 1$

-4

What did you discover when you compared your answers? Explain your rationale.
